海外TECH DEV Community Introduction To Python Programming - part 3 https://dev.to/akinnimimanuel/introduction-to-python-programming-part-3-32ma Introduction To Python Programming part Hello and welcome to Part of the series “Introduction to Python Programming If you have not gone through the previous episode kindly find the links below introduction to Python programming part oneIntroduction to Python programming part two Boolean ValuesYou can evaluate any expression in Python and get one of two answers True or False Python delivers the Boolean result after evaluating the expression when two values are being compared print gt returns Trueprint returns False print lt returns FalseYou can also check the comparison of two values with a conditional statement a b if b gt a print b is greater than a else print b is not greater than a prints out b is not greater than a Evaluate Values and VariablesYou can evaluate any value using the bool function and it will return either True or False print bool Hello returns Trueprint bool returns True Most Values are TrueIf a value has content of any kind it is evaluated to True almost immediately Any string is True except empty strings Any number is True except Except for empty ones every list tuple set and dictionary are True The following will return true bool Earth returns Truebool returns Truebool apple cherry banana returns TrueCertain values are false Except for empty values like the number and the value None there aren t many values that evaluate to False The following will be evaluated as false bool False returns Falsebool None returns Falsebool returns Falsebool returns Falsebool returns Falsebool returns Falsebool returns FalseBrace up people because we will be using the remaining part of this series to talk about Python data collections They are very powerful tools at our disposal that will enable us to perform and create beautiful applications with Python The four Python collections areListsTupleSetsDictionary Python ListsLists allow multiple elements to be maintained in a single variable Lists are created using square brackets Creating a listCities Sydney New York London Paris print cities returns Sydney New York London Paris List ItemsList items can have duplicate values and are ordered and changeable List items are indexed the first item has an index the second item has an index etc Properties of a lista Lists are ordered which means the items in a list have a defined order in which they are arranged When a new item is added to a list it will be placed at the end of the list b List items are changeable You can add or remove a list item after its creation c Lists allow duplicates of list items i e you can have the same items in a list Mylist Sydney New York London Paris New York London print Mylist d You can determine the length of a list by using the len function print len Mylist e Any data type can be used for list items list carrot pearl apple list string data typelist numeric list data typelist True False False boolean list data typef A list can contain different data types list Hello False male list with strings numeric and boolean data types g List constructor We can also use the list constructor to create a new list instead of the square bracket thislist list apple samsung xiaomi note the double round bracketsprint thislist h Finding items on a list You can access list items by using the index number which is listed with each item Printing the third item on the listthislist apple samsung xiaomi print thislist returns XiaomiNOTE the first number has an index number of Negative IndexingNegative indexing means starting from the endThe last and next to last items are indicated by the numerals and respectively Printing out the last item of a listthislist apple samsung xiaomi print thislist returns xiaomi Range of IndexesYou can provide a range of indexes by indicating the range s beginning and ending points A new list containing the requested items will be returned when a range is specified Return the third fourth and fifth item in the listthislist apple samsung xiaomi blackberry Nokia Tecno sony print thislist returns xiaomi blackberry and nokiaIf the start value is omitted the range will begin with the first item thislist apple samsung xiaomi blackberry Nokia Tecno sony print thislist This code returns the items from the beginning but will exclude NokiaThe range will continue to the end of the list if the end value is omitted thislist apple samsung xiaomi blackberry Nokia Tecno sony This code returns the items from “xiaomi to the endprint thislist Range of Negative IndexesIf you want to start the search at the end of the list enter negative indexes thislist apple Samsung Xiaomi blackberry Nokia Tecno Sony This code returns the items from “blackberry to but NOT including “sony print thislist Python TuplesA tuple is a collection that is ordered and unchangeable Tuples are written in round brackets Creating a tuplethistuple java javascript python print thistuple Tuple ItemsDuplicate values are permitted for tuple items which are ordered and immutable The first item in a tuple is indexed and the second item is indexed etc The major difference between a list and a tuple apart from how they are created is that a list item can be changed but a tuple item can t be changed To determine the tuple length the len function is also used print len thistuple Python will not recognize a single item as a tuple unless you add a comma after the item to make it a tuple thistuple apple print type thistuple Data types Any data type can be used for tuples A tuple can contain numeric string or boolean values The tuple ConstructorLike a list it is also possible to use the tuple constructor to make a tuple Using the tuple constructor to make a tuplethistuple tuple newyork lagos capetown note the double round bracketsprint thistuple SetSets are written with curly brackets thisset apple banana cherry print thisset Sets are unordered so you cannot be sure in which order the items will appear Set ItemsSet items don t allow duplicate values are unsorted and can t be changed Set items can be of any data type and a set can contain different data typesset Europe True male print set The set ConstructorIt is also possible to use the set constructor to make a set thisset set apple mango pineaple note the double round bracketsprint thisset Python DictionariesPython dictionaries make use of key value pair storage for storing their data A dictionary is ordered the items can be changed and it doesn t allow duplicates of items The key value pairs of data are wrapped inside a curly bracket Creating a dictionarythisdict “Brand “Apple “Model “Macbook pro “Year print thisdict Dictionary ItemsItems in the dictionary are arranged editable and do not permit duplication Key value pairs are used to exhibit dictionary entries and the key name can be used to refer to a particular entry Print the “model value of the dictionarythisdict “Brand “Apple “Model “macbook pro “Year print thisdict brand Dictionary LengthUse the len function to find out how many items a dictionary has Data type in DictionaryItems in dictionaries may have values of any data type The dict ConstructorWe can also use the dict constructor to create a dictionary Using the dict constructor to make a dictionarythisdict dict name Akinnimi age country Nigeria print thisdict SUMMARY OF THE DIFFERENCES BETWEEN THE FOUR PYTHON DATA TYPE COLLECTIONSLists tuples sets and dictionaries are all different types of data structures in Python each with their own unique properties Lists Mutable After creation elements may be added deleted or updated Ordered Elements keep the order in which they were inserted Allows elements to be duplicated TuplesImmutable Once created an element cannot be altered Ordered Like lists elements keep the order in which they were inserted allows elements to be duplicated Sets Mutable After creation elements can be added or removed Unordered There is no innate order in the elements prohibits the use of elements twice DictionaryMutable After creation key value pairs may be added changed or eliminated Unordered Prior to Python there was no assurance of order for dictionaries Insertion order is preserved in Python and beyond Keys must be unchangeable and distinct Values may include duplicate values and be of any type In conclusion dictionaries are collections of key value pairs with the option of order preservation sets are unordered collections of unique components and lists are flexible and ordered collections Tuples are similar to lists but immutable There is a whole lot we can still do with the four data structures I will recommend you read more about them in the
