07. Prime Number Checker Beginner Projects

To build a simple, beginner-friendly Prime Number Checker application in Python, here’s a structured approach to help you:

1. Basic Features

• Input: Allow the user to enter a number.
• Prime Check Logic: Implement logic to check if the number is prime.
• Output: Inform the user whether the number is prime or not.

2. Workflow

• User Input: Get a number from the user (positive integer).
• Prime Check:
  • If the number is less than 2, it’s not prime.
  • For other numbers, check if they have any divisors other than 1 and themselves.
• Display Result: Show the result (prime or not prime) to the user.

3. Error Handling

• Handle invalid inputs (e.g., non-numeric or negative values).
• Give clear feedback if the user enters something other than a positive integer.

4. Optional Features

• Multiple Checks: Allow the user to check more than one number in a session.
• Exit Option: Provide a way to exit the program when the user is done.

This will give you practice with conditionals, loops, user input, and error handling.
