Functions accept arguments that can contain data. The function name is followed by parenthesis that list the arguments. Simply separate each argument with a comma to add as many as you like.

Example 1: Python Function Arguments:

In the above example, the function add_numbers() takes two parameters: a and b.

Function Argument with Default Values:

In Python, we can provide default values to function arguments. We use the = operator to provide default values

In the above example, the function definition Here, we have provided default values 7 and 8 for parameters a and b respectively.

Python Keyword Argument

A function must always be called with the appropriate number of parameters by default. In other words, if your function requires 2 arguments, you must call it with 2 arguments, not more or fewer.

First name from the function declaration is paired with first name from the function call. Similar to how last name in the function specification corresponds to last name in the function call.
