我有以下字符串:

I checking capital or simple letter follows after each underscore symbol, but not all capital..
我在每个下划线的符号后面都要检查大写字母或简单字母，但不是所有的大写字母。
Example:
例子:
step_User_Save_Action_Details - Should return False
step_User_Save_Action_Details -返回False。
step_user_save_Action_Details - Should return True
step_user_save_Action_Details——应该返回True
step_user_save_action_details - Should return True
step_user_save_action_details——应该返回True

试试这个，但似乎并不是你想要的

You can use a negative lookahead based regex:
您可以使用基于负面前瞻的regex:
/\bstep(?!(?:_[A-Z][a-zA-Z]*)+\b)(?:_[a-zA-Z]+)+\b/
RegEx演示
(?!(?:_[A-Z][a-zA-Z]*)+\b) is a negative lookahead that will fail the match if underscore are all immediately followed by a capital letters.
(?!) (?:_[a-z][a- za -z]*)+\b)是一个负面的前视，如果下划线后面紧跟着一个大写字母，就会导致失败。
