哥德巴赫猜想:任意大于等于4的偶数都可以写成两个质数之和。请输入一个大于4的整数,编写Python程序对其进行检验。 import math def prime(m): if m<=1:return False k=① for i in range(2,k+1): if m%i==0:return False return True #由于4=2+2这组数据没有问题!下面,我们只检测大于4的偶数 n...
本题考查Python程序设计相关内容。分析程序段,推知: (1)该函数功能是判断x是否是素数,由素数相关知识,可得:在[2,x-1]范围内,若没有能整除x的数i存在,则说明x为素数,此时应返回True,故下划线处答案为:return True。 (2)将27代入函数,执行循环程,当i=3时,x%i==0成立,执行return False,则输出结果为:Fals...
A wide range of human diseases are associated with diverse genetic alterations that may be responsible for initiating, promoting or otherwise modifying the course of a given disease. These alterations can be quite complex; for instance, cancer genomes typically contain a repertoire of single nucleotide...
