海外TECH	DEV Community	Why you should create a GitHub profile README (as a job seeking dev)	https://dev.to/patricklemmer/why-you-should-create-a-github-profile-readme-as-a-job-seeking-dev-1e86	Why you should create a GitHub profile README as a job seeking dev Let s get straight to the point To understand why a profile README is a good idea for job seeking devs let s see what this file is commonly used for When you create a GitHub repo for your project you also create a README md file for this repo and you do it for a specifc reason That could be a you want to offer a central point for your projects documentation A place where users can refer back to to get information about your project B It could be used to hold any kind of information about the technical specs of your project or c to highlight specific stuff about your project that otherwise lives somewhere in a hidden place unavailable to some users readers There are other reasons why you create a README file but the point is you use it to highlight document inform and so on One thing you want to do as a job seeking dev is to highlight document inform and so on about you your skills and your projects You may have other social profiles where you already do this or some of it but since you likely host the code for your projects in a GitHub repo or any other Git repo hosting platform it is a good idea to make use of the profile README If you have a LinkedIn profile you will know that this is mainly used to build a profile around you and your professional experience The same way you can use your GitHub profile to build a profile around you and your code What and how much information you put into the README is totally up to you It will however round off your complete application package very well as you have a nice personal profile whether the recruiter or hiring manager checks out your LinkedIn your GitHub or even both Here is how you create one You create a new repoThe repo MUST have the same name as your GitHub username And you need to initialize it WITH the README file I have already created mine hence the notification in the screenshot Now you have a repo with only one file The README file At this point you can get creative and add whatever information you would like to use to highlight document inform and so on about you and your code A quick Google search for GitHub profile README examples will give you enough ideas to get started You can also use templates or template generators to build this out These will give you the Markdown wich yout then simply have to add to the file and commit the changes Here are two links that will help you writing Markdown yourself Basic writing and formatting syntaxGitHub Markdown CheatsheetOne more thing If you have any other social profiles such as LinkedIn Twitter etc try to be consistent with your profiles While each platform serves a different purpose which means you have to create profiles around this purpose keep things like username if available profile photo summary headline etc consistent across these platforms That way you can be found easier and it also gives your personal brand a professional and mature look	2023-02-20 14:33:49

海外TECH	DEV Community	How to start with Python - The Basics for Absolute Beginners	https://dev.to/aradwan20/how-to-start-with-python-the-basics-for-absolute-beginners-lf1	How to start with Python The Basics for Absolute BeginnersPython is a popular programming language known for its simplicity and ease of use One of the fundamental concepts in programming is the use of variables In this tutorial we will discuss the basic aspects of python language starting with variables and data types What are variables A variable is a named storage location in a computer s memory that is used to store data The data stored in a variable can be changed or manipulated during the execution of a program Variables are given a name and a data type which defines the type of data that can be stored in the variable Why are variables important Variables are important because they allow us to store and manipulate data in a program Without variables we would have to write the same data over and over again in a program which would be both time consuming and error prone By using variables we can store data once and then refer to it multiple times throughout the program What are data types in Python In Python there are several data types that can be used to store data in variables Some of the most commonly used data types include Integer int An integer is a whole number positive negative or zero that can be stored in a variable For example age Float float A float is a decimal number that can be stored in a variable For example height String str A string is a sequence of characters that can be stored in a variable For example name John Doe Boolean bool A boolean is a data type that can only store two values True or False For example is student TrueList list represents a collection of values such as and can be stored in a variable For example numbers Tuple tuple similar to lists but the values cannot be changed after the tuple is created and can be stored in a variable For example person John Dictionary dict represents a collection of key value pairs and can be stored in a variable For example person name John age weight Set set represents a collection of unique values and can be stored in a variable For example unique numbers Declaring Variables in PythonTo declare a variable in Python you simply need to assign a value to a variable name For example name Jane Doe In this example the variable name is assigned the string value of Jane Doe Using Variables in PythonOnce you have declared a variable in Python you can use the variable in various ways in your program For example you can use the value stored in a variable to perform calculations or to print the value to the screen For example to print the value stored in the name variable to the screen you can use the following code print name output Jane DoeYour First Python Program with PythonLet s write another simple Python program that calculates the area of a circle This program will take the radius of the circle as input and calculate its area Here is the code radius float input Enter the radius of the circle area radius radiusprint The area of the circle with radius radius is area When you run the program it will ask you to enter the radius of the circle Enter a value and press Enter You should see the output of the program which is the area of the circle with the given radius Working of the ProgramIn this program we first take the radius of the circle as input from the user using the input function The input function returns the input as a string so we need to convert it to a float using the float function Next we calculate the area of the circle using the formula radius radius Finally we use the print function to display the result This program demonstrates how you can use variables and the input function to take input from the user perform calculations and display the result Before We Begin and dig deeper into codingBefore we dive into the coding part let s go over a few important points Overcoming the fear of coding Many people feel intimidated by coding and think it is difficult to learn However just like any other skill coding can be learned with practice and dedication Don t be afraid to make mistakes as they are an important part of the learning process Coding is a form of communication Just like spoken languages coding is a way to communicate with computers With programming you can give instructions to a computer to perform specific tasks Basic math skills are all you need Although coding may seem complex it only requires basic arithmetic skills Most of the time coding involves logical thinking and problem solving skills rather than complex mathematical calculations With these points in mind let s get started with learning the fundamentals of Python Python Fundamental ConceptsBefore we start writing programs there are a few basic concepts in Python that we need to understand Let s go over these concepts now Numbers and Texts In Python there are two main data types that we use to store values numbers and texts Numbers can be integers or floating point numbers while texts are called strings For example age weight name John Doe In this example age is an integer weight is a floating point number and name is a string Print Output The print function is used to display the output of a program You can print numbers strings or any other data type For example print print print John Doe This will output the following John DoeThese two concepts are the building blocks for writing programs in Python In the next lesson we will learn how to use these concepts to write simple programs Using numbers texts comments and print in programIn programming we can use fixed values directly in our programs known as literals Here are the most commonly used literals in Python Integers int Integers are whole numbers without any decimal parts For example age temperature In this example age is an integer with the value of and temperature is an integer with the value of Floating point Numbers float Floating point numbers are numbers with decimal parts For example height weight In this example height is a floating point number with the value of and weight is a floating point number with the value of Strings str Strings are sequences of characters wrapped in quotation marks In Python you can use either single quotes or double quotes to create strings For example name Jane Doe address Main Street In this example name is a string with the value of Jane Doe and address is a string with the value of Main Street These are the most commonly used literals in Python By understanding these data types you can store different types of values in your programs and use them to perform various operations Printing Numbers and Strings in PythonIn Python we use the print function to display output on the screen In this section we will learn how to print numbers and strings Let s start with printing numbers print print print This will output the following As you can see we can simply pass a number as an argument to the print function and it will print the number on the screen Next let s look at how to print strings print Hello World print My name is John This will output the following Hello World My name is John o print a string you need to wrap the text in quotes You can use either single quotes or double quotes the print function in more detail and also look at common mistakes that you might face while using print print an integerprint Output print a stringprint Superheroes Output Superheroes create a variablecapital Paris print the capital variableprint capital Output Paris print multiple items at onceprint Spiderman Output SpidermanIn this example we have used the print function to print integers strings and variables We have also shown how to print multiple items at once Note that when we print strings the outer quotation marks are not displayed in the output Common Mistakes with printForgetting to put quotes around stringsWhen printing strings make sure to wrap the text in either single quotes or double quotes or else you will get an error Using commas instead of the operator to concatenate stringsTo concatenate two strings you need to use the operator not a comma For example print Hello World Output Hello WorldThe print function is a useful tool for displaying output in Python By understanding the print function and avoiding common mistakes you can make sure that your programs produce the output you expect That s it With these examples you now know how to print numbers and strings using the print function in Python Python CommentsIn programming we can make computers ignore certain parts of the program by using comments In Python a comment starts with the symbol For example This is a commentprint In this example the line This is a comment is a comment and it is ignored by the computer The print function is executed and the output will be Why Use Comments in Python Even though comments are ignored by the computer they play an important role in helping other people who read the code understand it For example if you are working on a project with a team of developers comments can help them understand the logic and thought process behind the code In addition comments can also be used to temporarily disable a portion of the code or to explain the working of a particular section of the code For example Calculate the area of a circleradius float input Enter the radius of the circle area radius radiusprint The area of the circle with radius radius is area In this example the comment Calculate the area of a circle explains what the code below it does In conclusion comments are a useful tool in programming and it is a good practice to add comments to your code to help others understand it Common mistakes with creating variables and the use of print functionAs a beginner in Python it is common to make certain mistakes In this section we will cover two common mistakes that you might make Spelling Errors Spelling errors are a common cause of errors in programming For example if you use the wrong variable name or misspell a word you will get an error For example salary Error because of a spelling mistakeprint salary icome This will result in an error File lt string gt line in lt module gt NameError name salary icome is not definedIn this case the error message clearly states that salary icome is not defined It is important to note that Python is case sensitive This means that salary and Salary are considered to be two different variables Adding Spaces at the Beginning In Python indentation has a special meaning So if you add unnecessary spaces at the beginning of a line you will get an error For example print Hello ErrorIf you run this code you will get an error because there is a space at the beginning of the line In conclusion being aware of these common mistakes can help you avoid them and write error free code in Python Error Due to Quotation Marks A common mistake made by beginners is forgetting to add the ending quotation marks in a string For example print Hello Errorn this case Python doesn t know what Hello is It is not a string because it doesn t have the ending quotation mark and it is not a variable because you cannot use quotation marks in variable names Forgetting Commas in the Print Function Another common mistake is forgetting to use commas in the print function For example age print Age age ErrorIn this case Python interprets Age age as a single item Since it is neither a string nor a variable you will get an error In conclusion being aware of these common mistakes can help you avoid them and write error free code in Python Introduction to Operators in PythonUp until now we have learned about values variables and how to print them However in real world projects we need to perform operations on these values and variables not just print them In this lesson we will learn about operators which are special symbols that allow us to perform operations on values and variables For example number total number print total In this program is an operator that is used to perform addition Here is a list of operators we will learn in this lesson OperatorSyntaxMeaning x yAddition x ySubtraction x yMultiplication x yDivision x yRemainder x yExponentiationLet s start with the operator The OperatorThe operator is used to add two operands values or variables For example x y using to perform additiontotal x y print total Output n this program total x y first computes the sum of x y and Then the result is assigned to the total variable We can also perform addition directly without using an extra variable For example x y print x y Output In this example the line print x y first computes the sum of x and y Then the result is directly printed on the screen The OperatorThe operator subtracts the value on the right from the value on the left For example x y result x yprint result Output In this program result x y first subtracts y from x Then the result is assigned to the result variable Here is another example x y print Result x y This statement prints the string Result and then prints the difference of x and y The operator works by subtracting the value on the right from the value on the left The OperatorThe operator multiplies two values or variables For example number number computing the product of number and numberproduct number numberprint product Output In this program we first define two variables number and number and store values in them Then we calculate the product of number and number and store it in the product variable Finally we print the product using the print function Here is another example number computing the product of number and product number print product Output In this program we define a variable number and store a value in it Then we calculate the product of number and and store it in the product variable Finally we print the product using the print function The OperatorThe operator is used for division For example number result number print result Output In this program we define a variable number and store a value in it Then we divide number by and store the result in the result variable Finally we print the result using the print function Here is another example number result number print result Output In this program we divide number by and store the result in the result variable Finally we print the result using the print function Note that the operator always returns a float value In this case divided by results in and not The OperatorThe operator computes remainder when one number is divided by another divisor dividend compute remainderremainder dividend divisorprint remainder Output In the above program divided by is with as the remainder The OperatorThe operator computes the exponential power of a number Let s take an example base power result base powerprint result Output ConversionsWe can convert data of one type to another using type conversion functions In Python there are types of conversion functions int x Converts x to an integer float x Converts x to a float For example convert string to integerstring number int string print number Output convert integer to floatinteger float number float integer print float number Output convert string to floatstring float number float string print float number Output User InputsIn Python we can also ask the user for input and assign it to a variable This can be done using the input function For example name input Enter your name print Your name is name User Input Without Promptfull name input print Full name full name The full name input statement doesn t print anything but makes the program wait until the user gives input When we don t provide a prompt message in the input function the user might not know what to enter But when we provide a prompt message it gives clear instructions to the user about what kind of input is expected In the above example when the user runs the program it waits for the input without displaying any prompt message Hence it s always a good practice to provide a clear prompt message to the user Let s put conversion with user inputs together in the next example Take inputs from the usernumber input Enter a number number input Enter another number converting the strings to integersnumber int number number int number product number numberprint Product product Sample Output Enter a number Enter another number Product ConclusionThe article covers the basic concepts of Python programming It discusses numbers including integers and floating point numbers and strings which are sequences of characters wrapped in quotation marks Variables are introduced as a way to store data for later use in the program and the print function is explained as a way to display output The article also covers the use of comments in a program which starts with a symbol and various arithmetic operators Data conversion is discussed including the use of the int and float functions to convert data types The article concludes with a discussion of the input function which is used to get input from the user and always returns input as a string	2023-02-20 14:04:59
