What Is Function and how it works and Advantages ?
Function is a group of statements which perform a particular task.
Function is a reusable block of code which performs operations specified in the function. They let you break down tasks and allow you to reuse your code in different programs.
Rules to define a function in Python:
> Functions blocks begin def followed by the function name and parantheses ().
> There are input parameters or arguments that should be placed within these parantheses ().
> You can also define parameters inside these parantheses.
> There is a body within every function that starts with a colon(:) and is indented.
> You can also place doccumentation before the body.
