Python allows for user input.
That means we are able to ask the user for input.
The method is a bit different in Python 3.6 than Python 2.7.
Python 3.6 uses the input() method. 
Python 2.7 uses the raw_input() method. 
The following example asks for the username, and when you entered the username, it gets printed on the screen:
  username = raw_input("Enter username:")
print("Username 
  is: " + username)
Python stops executing when it comes to the input() function, and continues 
when the user has given some input.
