使用输入时，只有 if 语句有效，但 elif/else 无效
When using input, only the if statement works but not elif/else
使用输入时，它似乎只适用于我的 If 命令，但不适用于我的 elif/else 语句。我不认为这是语法或间距问题。如果能帮我解决这个问题，我将不胜感激。
我基本上只是让这个脚本通过输入是或否来自动化流程图。如果用户输入 Yes 或 No，则会出现以下提示。

问题出在你的条件上，它总是产生一个真值。
表达式 identify == 'Y' or 'yes' or 'y' or 'Yes' or 'YES' 将 return 为真（如果标识 == 'Y'）或将 return 'yes'.
两者（True 和 'yes'）都是真值。
您想将表达式 identify == 'Y' or 'yes' or 'y' or 'Yes' or 'YES' 替换为 identify in ['Y', 'yes', 'y', 'Yes', 'YES']。
