Answer»

A function is a block of organized, reusable code that is used to perform a single, related action. Functions provides better modularity for your application and a high degree of code reusing.As you already know, Python gives you many built-in functions like

print( ) etc. but you can also create your own functions. These functions are called

user – defined functions.

Syntax: def functionname(parameters):

“function_docstring”

function_suite return[expression]

By default, parameters have a positional behavior, and you need to inform them in the same order that they were defined.

Example:

Here is the simplest form of a Python function. This function takes a string as input parameter and prints it on standard screen.

def printme(str):

“This prints a passed string into this function”

print str

return
