def function_name(<arguments):

Example of a simple function which takes no arguments.

Function which takes arguments and returns addition.

Function passing arguments with key.

Default value of argument 

We can set default value for argument, if value is not passed for that argument it takes default value.

Passing arbitrary arguments using *args

If the number of argument function is not fixed we can use arbitrary argument

Passing arbitrary keyword arguments using **kwargs

We can pass arbitrary number of arguments with some values.
