我是python的新手，尝试学习一些基础知识，因此尝试开发一个小型的HANGMAN游戏。我陷入了while循环格式中，除了HANGMAN列表中的ZERO索引元素外，结果中什么也没显示。
import random
HANGMAN = (

在while循环中没有任何作用。
答案 0 :(得分：2)
我的代码在我的机器上可以正常工作了，并且语法和空白处都比较精细。总体而言，您的方向正确！ while循环仅返回HANGMAN循环的第一个元素的原因是因为代码实际上并未减小attempt的值。你在做
attempt=-1
代替
attempt -= 1
，并且每次迭代都将attempt设置为-1。实际上，使用-=运算符会减少它。
也存在语法错误的变量声明（您在Python中使用=而不是==分配变量）和一些不一致的变量用法（attempts而不是attempt ，searchmore和searchMore等）。
最后，我将单词列表移到了while循环之外。您无需在while循环每次运行时重新创建该列表。
