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 factor in that range, th...

通过前面两节课的学习,大家对 Python 中的分支结构和循环结构已经有了初步的认知。分支结构和循环结构是构造程序逻辑的基础,它们的重要性不言而喻,但是对于初学者来说这也是比较困难的部分。很多人对分支结构和循环结构的语法是能够理解的,但是遇到实际问题的时候又无法下手;看懂别人的代码很容易,但是要自己写出类似的...
However, one can find such a pair of prime numbers, if any, for a given even number. The problem here is to write a program that reports the number of all the pairs of prime numbers satisfying the condition in the conjecture for a given even number. 谙忆 2021/01/21 3550 浙大版《C...
Back to normal. ① 上下文管理器是LookingGlass的一个实例;Python 在上下文管理器上调用__enter__,结果绑定到what。 ② 打印一个str,然后打印目标变量what的值。每个print的输出都会被反转。 ③ 现在with块已经结束。我们可以看到__enter__返回的值,保存在what中,是字符串'JABBERWOCKY'。
