海外TECH	DEV Community	Variables in Python	https://dev.to/princeibs/variables-in-python-3foe	Variables in PythonA variable in programming is generally a container or location in the computer s memory used to store values temporarily Variables in Python are nothing different from the general programming definition of a variable Values stored in the variable can then later be used or modified in our programs This article discusses all the basics you need to know in Python programming language Table of ContentsWhat are variables Variables in PythonVariable Naming conventionVariable declaration and usageReassigning variablesOperation on variablesVariable scope Local and global variablesConclusion What are Variables Variable are reserved locations in the memory of the computer used to hold values that can be used later Because the computer stores variables in the Random Access Memory RAM variables are created in the memory only when our program is in execution and are lost immediately after the program is terminated What this means is that the value of a variable can only be accessed when a program is running When the program has finished execution these variables are not accessible anymore from anywhere in the computer In order to use them again you will have to run the program once again If you wish to store and retrieve variable values in your programs consider using a file or database to store these variables Variables stored in files and databases are stored in the secondary storage of the computer e g Hard Disk Drive HDD and remains for as long as you want them They can also be retrieved from the computer s memory even after shutting down and booting up the computer Variables in PythonIn Python variables are nothing different from the definition above Python allows us to create variables and use them in our programs as well as manipulate the values of these variables Variable Naming ConventionBelow are some of the rules that variables you must abide by when naming variables in Python Do not use reserved keywords as a variable name For example keywords like class int def while else try e t c You cannot use special characters such as amp e t c when naming variablesVariable names are case sensitive For example age and Age are two different variables Variable names should start with an alphabet or an underscore character A variable name can only contain the characters A Z a z and underscore You cannot start the variable name with a number Variable Declaration and UsageVariables in python can be declared and used in different ways Here we will be exploring some of the ways variables can be declared and used The snippet below declares and used the variable message prints the value of message to the consolemessage Hello World print message output Hello World The snippet above is the simplest way you can declare a variable in Python But wait what if I need to make my variable names more descriptive Python has got your back According to PEP Style guide variable names should be lowercase with words separated by underscores as necessary to improve readability In a situation where you might want to use long and descriptive variable names you can simply separate it with an underscore like in the snippet below long and descriptive variable namessecret message Hey here is my secret print secret message output Hey here is my secretPython also allows you to declare variables in a more flexible and dynamic way Unlike other statically typed programming languages like Java Python is a dynamically typed language and you don t need to care much about the type of a variable during declaration You can declare multiple variables of different types on the same line Let s see how this looks Declare multiple variables in a single line doing it the conventional wayname Prince age hobby Swimming print Name name Age age Hobby hobby doing it the Python waymy name my age my hobby Prince Swimming print Name my name Age my age Hobby my hobby output Name Prince Age Hobby Swimming Name Prince Age Hobby Swimming Reassigning VariablesPython allows you to reassign variables after they are declared just like most programming languages allow you to This process is known as “writing into a variable When you reassign a variable the previous value is lost and the new value is then stored Reassigning variablesmy age print my age reassign the value of my agemy age print my age output The value of my age was initially but after printing it on the console and then reassigning it the value changed to Operation on VariablesYou can also perform some operations on the values of your variables This is one of the great benefits variables give to us In a situation where you want to perform operations on a very lengthy value many times in your programs You don t need to use that length value everywhere in your program You can simply store the value with a shorter variable name and use it throughout your program Let s try this out Operations on variablesPI radius perimeter PI radiusprint perimeter output You can perform any arithmetic operations on numbers in Python From the snippet above we can also operate on variables and literals from the code example provided they are all numbers either integers or with decimal points The value from the code example is long and you might have a hard time holding it in your head Storing it in PI makes it easily accessible and can be used throughout our programs Strings are also not left out here as well as you can perform operations on strings as shown in the code example below String operationsmsg Hello msg World full msg msg msgprint full msg output HelloWorldThe most common operation on string is concatenation This is simply appending one string to the end of the other using the operator You can only concatenate a string with another string If you try to do otherwise Python will throw a TypeError The operator can also be used on strings But instead of appending to the end of the string it rather duplicates the string according to the integer value specified String operationsfav language Python output fav language print output output PythonPythonPythonPythonPythonAlso note that the value specified must be an integer Using otherwise will also throw a TypeError Variable Scope Local and Global VariablesVariables declared in the programs we have written so far are available throughout the program This means it can be accessed from anywhere in the program But things begin to get complicated when we start writing complex programs that involve functions which carry out a particular task This is where the concept of variable scope come in The scope of a variable is the region of our program where the variable can be accessed A variable can either have two scopes Local and Global A local variable is a variable accessible within the function or method it is defined This is useful when we want to isolate a variable from the remaining part of our program Variable scope local variable def some function my real age print my real age my real age is locally available in some functionsome function execute some functionprint my real age my real age is not available outside some function output NameError name my real age is not definedWhen some function is executed it prints out the value of my real age to the console because my real age is defined inside the function But again when we tried to print my real age outside some function a NameError was thrown because my real age is only available inside some function and not throughout the program This is because my real age is a local variable A global variable is a variable accessible throughout our program It remains the same throughout our program and also throughout the module Use the global variable when you want to use the variable throughout the methods and functions of your program Let us use the same example from above but this time making my real age a global variable Variable scope global variabledef some function global my real age my real age globally available throughout this program print my real age some function print my real age my real age is now available outside the some function output The program above runs successfully without any errors because my real age is now declared as a global variable Declaring variables either local or global is useful in cases where you wouldn t want variables to clash in your Python packages and modules Other programming languages like Java use class variables instance variables and local variables for this concept But it is more simplified with just local and global variables as presented by Python ConclusionHaving a good knowledge of variables in any programming language is as important as learning the language itself This article discusses an overview of variables in Python It starts with a general view of a variable and then narrows down to the Python view of a variable And then discussed the naming convention of variables declaration and usage how to reassign variables the numerous operations you can perform on variables and finally the scope of a variable Check out the official Python documentation to know more about variables Feel free to drop your thoughts and suggestions in the discussion box I will be available to attend to them And also if you have any questions you can as well drop them in the discussion box	2021-12-04 17:13:14
海外TECH	DEV Community	Learning from the Masters: Design	https://dev.to/madsstoumann/learning-from-the-masters-design-35pg	Learning from the Masters DesignI recently bought two huge books on the history of graphic design from Taschen here s volume one As each book weighs more than kg I can only read for about half an hour or I ll lose the blood circulation in my legs I find it very inspirational to look at beautiful designs from these masters of design One thing I tend to do and can highly recommend is trying to recreate a classic design to something you can use on the web Take a look at this simple example How would you do this in HTML and CSS There s no right or wrong answer and you can probably think of many ways of accomplishing it And that s the beauty of it You can chose to do it in a known and familiar way or chose to challenge yourself going into unknown territory Either way I guarentee you ll learn something I always do Now back to the blue columns Notice how each blue column is half the size of the previous column In CSS Grid with the smallest column being fr it s columns display grid grid template columns fr fr fr fr fr Adding five lt div gt s inside a wrapper with class columns we get this Now it s only a matter of translateY ing columns adding aspect ratio to the first column and we have the initial version How can we “webify this That s up to your imagination For me the columns look a bit like books on a shelf so I ll add some dynamic font sizing using clamp and set the writing mode to vertical lr Let s look at another example from the book a beautiful old movie poster For me this screams “clip path so that s what I did a bunch of layered clip paths I also figured this could work as a custom header for an article so I wrote a small piece on the “imposter syndrome something I have to deal with from time to time One final exampleThere are hundreds of beautiful designs in the Taschen books currently I ve fallen in love with this I ve started to create the red circle using a radial gradient circle aspect ratio background image radial gradient circle hsl deg FFF hsl deg FFF hsl deg FFF hsl deg border radius But then again I might switch to svg animate the indivdual rings add text on a path etc Maybe you might find this whole “recreate classic designs in CSS silly or a waste of time but believe me it s fun challenging and always a great way to learn new stuff If you ve become inspired to do something similar or already have done please share links to your work in the comments	2021-12-04 17:12:48
