In this program, we have checked if num is prime or not. Numbers less than or equal to 1 are not prime numbers. Hence, we only proceed if the num is greater than 1. We check if num is exactly divisible by any number from 2 to num - 1. If we find a factor in that range, th...
首先,判断n是否小于等于1,如果是则返回False,因为素数定义中要求大于1。 然后,使用for循环遍历2到n的平方根(使用int(n**0.5)取整加1)之间的所有数。 在循环中,判断n是否能被当前数整除,如果可以,则返回False,因为找到了一个能整除n的数,说明n不是素数。 如果没有找到能整除n的数,则返回True,表示n是素数。

Prime Check Function (is_prime): This function checks if a number is prime by testing its divisibility from 2 up to the square root of the number. Main Function (print_first_10_primes): This function uses a while loop to find and print the first 10 prime numbers. It starts withnum =...

永远不会被打印,因为continue语句导致程序执行跳回到下一次迭代的for循环的起点,并且执行永远不会到达print('Hello!')行。 一个continue语句通常被放在一个if语句的块中,以便在某些条件下,在循环的开始处继续执行。让我们回到我们的代码,看看它是如何使用continue语句根据使用的密钥跳过执行的。
