Question

Write a program to find all prime numbers up to given number.

Answer 1

A prime number is divisible only by 1 and itself; test divisibility for each number from 2 to n.

n = int(input("Enter any number: "))

for num in range(2, n + 1):
    is_prime = True

    for i in range(2, num):
        if num % i == 0:
            is_prime = False
            break

    if is_prime:
        print(num, end=" ")
