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...
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...

The simplest solution in code is the brute force check, where you check one by one to see if there is a number that can divide the number you’re testing! If there isn’t one, then you know the number is prime. Here’s how a brute force check might work with code by first ...
```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...
统计元素的个数 是一种非常常见的操作,Python的collection包里 已经有一个Counter的类,大致实现了上面的功 能。 from collections import Counter items=["cc","cc","ct","ct","ac"] count = Counter(items) print(count) #Counter( $$ { 1 } ^ { 1 } c t $$:2, $$ ^ { \prime }...
