Functions Returning Values & Functions Arguments

Functions Returning Values & Functions Arguments:
Content:
? Function return value.
? Function return multiple values.
? Python Function Arguments .

Python also has the ability to return multiple values from a function call, something missing from many other languages. In this case the return values should be a comma-separated list of values and Python then constructs a tuple and returns this to the caller.

An alternate syntax when dealing with multiple return values is to have Python "unwrap" the tuple into the variables directly by specifying the same number of variables on the left-hand side of the assignment as there are returned from the function.
Python Function Arguments:
In Python, you can define a function that takes variable number of arguments. You will learn to define such functions using default, keyword and arbitrary arguments.
o Python Default Arguments
o Python Keyword Arguments
o Python Arbitrary Arguments.

we have called the function with multiple arguments. These arguments get wrapped up into a tuple before being passed into the function. Inside the function, we use a for loop to retrieve all the arguments back.
