Python：Sub不替换模式替换

Question

我一直在使用这段代码，似乎是一辈子的事情，似乎无法让它发挥作用。

translation = re.sub("'''[a-zA-Z0-9].*?'''", "<b>[what do I put here to copy [a-zA-Z0-9].*?</b>", translation)

Here I'm trying to replace " ''' [text] ''' " with " <b> [text] </b>. What would I have to put between <b> and </b> to make it copy across the text?

提前谢谢！

Answer 1

使用捕获组并按\1：

引用它

translation = re.sub(r"'''([a-zA-Z0-9].*?)'''", r"<b>\1</b>", translation)

Answer 2

translation = re.sub("'''([a-zA-Z0-9]*)'''", r"<b>\1</b>", translation)

那样的东西？
