如何在python中删除两个特定单词之间的文本
我已经使用beautiful soup包解析了一个url以获取其文本。我想删除条款和条件部分中的所有文字，即“关键条款：……T&C适用”一段中的所有文字 以下是我尝试过的：如何在python中删除两个特定单词之间的文本,python,regex,analysis,Python,Regex,Analysis,我已经使用beautiful soup包解析了一个url以获取其文本。我想删除条款和条件部分中的所有文字，即“关键条款：……T&C适用”一段中的所有文字 以下是我尝试过的： import re #"text" is part of the text contained in the url text="Welcome to Company Key.

你能在正则表达式的开头添加一个“^”符号来进行负面展望吗？这样terms n cons variables只会得到正则表达式没有过滤的东西？谢谢你的帮助。如果我有两个段落，每个段落中都写有术语和条件，一个段落之间有有用的文本呢。在这种情况下，代码也将删除它们之间的段落。如何解决这个问题？您可以创建两个捕获组：
“Key\s（.*）WORD（.*）&Cs”
