Functions

A function is a part of a program that can complete a certain task. For example, a function may be written that finds the average of three supplied numbers. Once written, it can be used many times without having to rewrite it over and over again.

Writing Functions

To define:

def func_name():

Any code inside the function should be indented until you want to exit the function.

You can put parameters - information passed to the function for use inside it - in a function as well. Here is a simple example:

def func_name(a,b,c):
	print(a+b)
	print(c)

func_name(3,7,"Hello") would print an output of:

10
"Hello"
