29 is a prime number 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 exactl

result=is_prime(17)print(result)# 输出True 1. 2. 运行上述代码,可以得到输出结果为True,说明17是一个素数。 性能优化 虽然上述代码能够正确判断一个数是否为素数,但在实际使用中,可以对其进行性能优化。由于素数只能被1和本身整除,因此在试除法中,只需要判断2到n的平方根范围内的数即可。
