Define function

Question

What are the best way to understand function and how to define them also how the function called with the input from user

Answer 1

The best way to understand function is to define your own function.

To define a function, use the def keyword.

Here is a simple function which is called with the user input.

def greeting(someone): # it uses keyword def, and has an argument 'someone' inside the parentheses
return "Hello, " + someone + "." # it uses keyword 'return' to return a string

name = input("Please enter your name: ") #e.g. Sumit maurya
print(greeting(name)) # it call the function greeting with an argument, and the returned string got printed
# Hello, Sumit maurya.

And it is a shortcut.
print(greeting(input("Please enter your name: ")))

All the steps are discussed in the introduction course "Making Your Own Function", "Function Arguments" and "Returning from Functions".
You can re-read them anytime as you want.
