Module Description

This module focuses on understanding and utilizing Python modules and packages, as well as practicing namespaces in functions.

Solution
Description: Task "How to Divide?":
- Create two modules, fake_math and true_math, each containing a divide function that handles division in different ways.
  - fake_math.divide: Returns an error message when dividing by zero.
  - true_math.divide: Returns infinity when dividing by zero (using math.inf).
- Import these functions into a main module using the as keyword to avoid name conflicts, and test them by passing values, including zero as the divisor.

Solution
Description: Task "Function Scope":
- Create a function test_function and define an inner function inner_function within it that prints a message. Call inner_function within test_function and test whether inner_function can be called outside of test_function.
