returning a value to the caller. Return without an expression is equivalent to returning None.
The syntax can be seen as follows:
def functionname (parameters): "Function _ Document String" function_suite return [expression]
(by default, parameter values and parameter names are matched in the order defined in the function declaration.) )
Next I'll give you a small example:
def printme (str): "Print incoming string to standard display device" print str return
