Prime Number Calculator

&copy

Sure! I can help you with that. Here's a simple prime number calculator in Python:

```python

def is_prime(n):

    if n <= 1:

        return False

    for i in range(2, int(n ** 0.5) + 1):

        if n % i == 0:

            return False

    return True

def prime_numbers(limit):

    primes = []

    for num in range(2, limit + 1):

        if is_prime(num):

            primes.append(num)

    return primes

# Example usage:

limit = int(input("Enter a number to find prime numbers up to that limit: "))

primes = prime_numbers(limit)

print("Prime numbers up to", limit, "are:", primes)

```

To use the calculator, you need to enter a number as the upper limit, and it will find all the prime numbers up to that limit.

Note that this calculator might take some time for larger limits, as it uses a basic algorithm to check for prime numbers. There are more optimized algorithms available for prime number generation, but this simple implementation should work for most small to moderate-sized limits.
