事实上,你几乎从来不希望你的程序从第一行代码开始,简单地执行每一行,一直到最后。流程控制语句可以决定在什么条件下执行哪些Python指令。 这些流程控制语句直接对应于流程图中的符号,所以我将提供本章中讨论的代码的流程图版本。图 2-1 显示了下雨时该做什么的流程图。沿着箭头所指的路线从头到尾走。 图2-1:告诉...
For example, you might want to write code for a service that starts up and runs forever, accepting service requests.Forever, in this context, means until you shut it down. The typical way to write an infinite loop is to use thewhile Trueconstruct. To ensure that the loop terminates natura...
Hi, I made this observation when analyzing Revelation book content. Grammar class will encounter infinite loop when processing text. I found exact character from the data. Thus on attachment I have provided two texts, the first one will ...

python并不像C语言有do/while语句,它只有一个while和for循环语句,有时你并不会提前知道什么时候循环会结束,或者你需要打破循环。一个不能再普通的例子就是正在按行迭代一个文件内容: file = open("some_filename", "r") while 1: # infinite loop ...
Infinite Loop 概念卡 定义 死循环是一种循环类型, 当一个循环永远无法终止 的时候,我们就说它是一个死循环。 隐喻 死循环就像是在一个没有出口的迷宫一直转圈,永远都跑不出这个迷宫。 第一个区别: for循环是在每一次循环的时候,按照从头到尾的顺序自动遍历,给变量name赋值列表中的元素; 而while循环是用一个...
