To write a Python program for prime numbers: Use a simple for-loop to check if a number is divisible only by 1 and itself. Here's an example code snippet: ```python # Check if a number is prime def is_prime(num): if num <= 1: return False for i in range(2, int(num 0.5) + 1): if num % i == 0: return False return True # Find and print prime numbers up to a certain limit limit = 100 primes = [i for i in range(2, limit) if is_prime(i)] print(primes) ``` This code finds prime numbers up to a specified limit.**
