Prime List in Python

Prime List in Python

One common task in programming is finding prime numbers. In Python, we can create a list of prime numbers using a simple and efficient algorithm.

Here is a sample code snippet to generate a list of prime numbers in Python:


def is_prime(num):
    if num < 2:
        return False
    for i in range(2, int(num**0.5) + 1):
        if num % i == 0:
            return False
    return True

def prime_list(n):
    primes = []
    for num in range(2, n + 1):
        if is_prime(num):
            primes.append(num)
    return primes

n = 20
print(prime_list(n))

This code defines two functions: is_prime() to check if a given number is prime, and prime_list() to generate a list of prime numbers up to a given limit.

By calling prime_list(n) with a specific value of n, we can get a list of prime numbers from 2 to n.

Prime numbers are essential in many mathematical and computational tasks. Knowing how to generate a list of prime numbers in Python can be a valuable tool for any programmer.
