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...
```python def is_prime(n): if n <= 1: return False for i in range(2, int(n ** 0.5) + 1): if n % i == 0: return False return True print(is_prime(2)) print(is_prime(10)) print(is_prime(7)) ``` 以上是编程语言基础知识试题及答案解析的内容。希望对你有所帮助! 开学特惠...
“For those students who have no experience with text-based coding or never thought that this was something that they would be interested in they have really enjoyed coding with Python. To me, that is very powerful to make what can be a difficult concept to learn (text-based coding) access...

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...
