13. To write a python program first n prime numbers.

 def is_prime(n):

    if n < 2:

        return False

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

        if n % i == 0:

            return False

    return True

def first_n_primes(n):

    count = 0

    num = 2

    while count < n:

        if is_prime(num):

            print(num, end=' ')

            count += 1

        num += 1

# Example usage:

n = 10

first_n_primes(n)
