Function Overloading:
- Create a class called MathOperations with methods for addition and multiplication.
- Implement function overloading by creating methods with the same name but different parameter types.
- Demonstrate the use of both methods by creating an object of the class and calling each method.
Operator Overloading:
- Create a class called ComplexNumber to represent complex numbers.
- Implement the __add__ method to overload the addition operator for complex numbers.
- Create two objects of the class and demonstrate the use of the + operator for complex number addition.

Division by Zero Handling:
- Write a function that takes two numbers as input and performs division.
- Implement exception handling to catch a ZeroDivisionError if the second number is zero.
- Print an appropriate error message in case of an exception.
File Handling with Try-Except:
- Modify the file reading assignment from earlier to include exception handling.
- Use a try-except block to catch and print any FileNotFoundError that may occur.

Module Creation:
- Create a Python module named calculator that contains functions for addition, subtraction, multiplication, and division.
- Import and use this module in a separate script to perform calculations.
Custom Exception Module:
- Create a module named custom_exceptions that defines a custom exception class InvalidInputError.
- Use this module in a script to raise and catch instances of the custom exception.

Encourage students to use meaningful variable names and provide comments explaining their code.
Remind students to handle exceptions gracefully, providing informative error messages.
Emphasize the importance of proper module organization and usage.
Encourage experimentation with different scenarios to ensure the correctness of the code.
Provide feedback on the usage of polymorphism, exception handling, and modules in their solutions.
