01. Simple Calculator Beginner Projects

To build a simple, beginner-friendly calculator application in Python, here's a structured approach:

1. Basic Features

• Basic Operations: Addition, subtraction, multiplication, and division.
• Input: The user will input two numbers and choose an operation.
• Output: Display the result of the operation on the console.

2. User Interface (Console-based)

• Display a menu where users can select the operation they want to perform (e.g., 1. Add, 2. Subtract, etc.).
• After choosing the operation, prompt the user to enter the numbers.
• Display the result and ask if they want to perform another calculation.

3. Error Handling

• Handle invalid inputs, such as entering a non-numeric value.
• Prevent division by zero errors by adding a check before dividing.

4. Exit Option

• Include an option to allow the user to exit the program gracefully, such as by entering q or selecting an "Exit" option from the menu.

5. Additional Features (Optional)

• Chain Calculations: Let the user perform operations on the result of previous calculations.
• Advanced Operations: Add more operations like square root, exponentiation, or modulus as you get more comfortable.
