Algorithms For Dummies

Calling functions

Functions can accept arguments (additional bits of data) and return values. The 

capability to exchange data makes functions far more useful than they otherwise 

might be. The following sections describe how to call functions in a variety of 

ways to both send and receive data.

Sending requirement arguments

A function can require the caller to provide arguments to it. A required argument 

is a variable that must contain data for the function to work. Open a copy of IPy-

thon and type the following code:

def DoSum(Value1, Value2):

    return Value1 

+ Value2
