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.
