Python Comments

 

Python Comments



Comments can be used to explain Python code.

Comments can be used to make the code more readable.

Comments can be used to prevent execution when testing code.

Creating a Comment

Comments starts with a #, and Python will ignore them:

Example

#This is a comment
print("Hello, World!")

Comments can be placed at the end of a line, and Python will ignore the rest of the line:

Example

print("Hello, World!") #This is a comment

A comment does not have to be text that explains the code, it can also be used to prevent Python from executing code:

Example

#print("Hello, World!")
print("Cheers, Mate!")

Python Lists

  Python  Lists mylist = [ "apple" ,  "banana" ,  "cherry" ] List Lists are used to store multiple items in a single variable. Lists are one of 4 built-in data types in Python used to store collections of data, the other 3 are  Tuple ,  Set , and  Dictionary , all with different qualities and usage. Lists are created using square brackets: Example Create a List: thislist = [ "apple" ,  "banana" ,  "cherry" ] print (thislist) List Items List items are ordered, changeable, and allow duplicate values. List items are indexed, the first item has index  [0] , the second item has index  [1]  etc. Ordered When we say that lists are ordered, it means that the items have a defined order, and that order will not change. If you add new items to a list, the new items will be placed at the end of the list. Changeable The list is changeable, meaning that we can change, add, and remove items in a list after it has been created. Allow Duplicat...

Python Variables

  Python  Variables Variables Variables are containers for storing data values. Creating Variables Python has no command for declaring a variable. A variable is created the moment you first assign a value to it. Example x =  5 y =  "John" print (x) print (y) Variables do not need to be declared with any particular  type , and can even change type after they have been set. Example x =  4         # x is of type int x =  "Sally"   # x is now of type str print (x) Casting If you want to specify the data type of a variable, this can be done with casting. Example x =  str ( 3 )     # x will be '3' y =  int ( 3 )     # y will be 3 z =  float ( 3 )   # z will be 3.0 Get the Type You can get the data type of a variable with the  type()  function. Example x =  5 y =  "John" print ( type (x)) print ( type (y)) Single or Double Quotes? Strin...
