Lesson 3.3 - Return vs. Print

• Every function returns a value.
• As soon as your function returns a value, no code below this return is executed
• In Python, if you do not specify a return value it defaults to None type. 
• A function's return value is commonly nested inside of other functions. For example:
• print( foo() )
• bar( foo( ) + 3 )
• foo( input('feed me a string' ) )
