2
Positional and Optional Arguments
Python is a fairly flexible language in terms of creating functions. This is especially true in setting function arguments - there are several different types of function arguments, and you can choose any of them depending on the problem you are solving. Let's now take a closer look at them.

3
Arbitrary Arguments
This section of the Python course covers *args and **kwargs, which allow you to handle variable numbers of positional and keyword arguments in functions. `*args` lets you pass any number of positional arguments, making functions more flexible. **kwargs allows you to pass any number of keyword arguments as a dictionary, which facilitates handling complex data structures efficiently.
