问题描述
限时送ChatGPT账号..我正在寻找一个正则表达式来搜索我的 python 程序,以查找所有将 foo
而不是 bar
作为关键字参数传递给方法的行.我正在尝试前瞻和后视断言,但运气不佳.
I'm looking for a regex to search my python program to find all lines where foo
, but not bar
, is passed into a method as a keyword argument. I'm playing around with lookahead and lookbehind assertions, but not having much luck.
有什么帮助吗?
谢谢
推荐答案
如果您有一个字符串 foo
想要查找,另一个字符串 bar
不能是目前,你可以使用这个:
If you have a string foo
that you want to find and another string bar
that must not be present, you can use this:
^(?!.*bar).*foo
创建一个完全满足您所有要求的正则表达式非常困难,因为 Python 代码不是常规语言,但希望您应该能够使用它作为起点来获得足以满足您需求的东西.
Creating a regular expression that exactly meets all your requirements is very difficult as Python code is not a regular language, but hopefully you should be able to use this as a starting point to get something good enough for your needs.
