我的代码冻结并使用了很多 CPU 功能。 (Python)

Question

我正在尝试制作一种类似 AI 的脚本，它会计算出您的短语。它仍在进行中，尚未完成。
每次猜测都应打印以下信息：
产生的文本： ......... 脚本产生的字符串。
文字的长度： ... 前面提到的字符串的长度。
文本的评分：..... 脚本会根据文本的长度和其中包含的字母对文本进行评分。
目标文本：......................它试图生成的文本。
出于某种原因，在第一个字符串之后代码冻结。我希望任何人都可以提供帮助，在此先感谢！

Answer 1

是因为执行卡在了第二次死循环。条件 (len(Ai)+lenVariation > len(goal)*2 or len(Ai)+lenVariation<round(len(goal)*0.5)) 在第一次执行后每次都满足，因此 if 语句永远不会评估为 True 并且 while 循环永远不会退出。

此外，请注意，您的 break 语句仅存在于 for 循环中，而不存在于 while 循环中，因此永远不会执行第二次 break 之后的语句。
