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 exactly divisible by any number from 2 to num - 1. If we find a fa...
下面是经过优化的素数判断函数: defis_prime(n):ifn<=1:returnFalseifn==2:returnTrueifn%2==0:returnFalseforiinrange(3,int(n**0.5)+1,2):ifn%i==0:returnFalsereturnTrue 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 结语 本文介绍了素数的定义,并使用Python编写了一个函数来判断一个数是否...
Python3 实例 一个大于1的自然数,除了1和它本身外,不能被其他自然数(质数)整除(2, 3, 5, 7等),换句话说就是该数除了1和它本身以外不再有其他的因数。 test.py 文件: # -*- coding: UTF-8 -*-# Filename : test.py# author by : www.runoob.com# Python 程序用于检测用户输入的数字是否为质数...

This function does a quicker # prime number check before calling rabinMiller(). if (num < 2): return False # 0, 1, and negative numbers are not prime. 当num不小于2时,我们也可以使用LOW_PRIMES列表作为测试num的快捷方式。检查num是否能被所有小于 100 的质数整除不会明确地告诉我们这个数是否是...
