英文:
Substitute a part of string (ignoring special characters)
问题
假设我有一个字符串列表，并想使用 re.sub 来替换其中的不同部分。我的问题是有时这种替换包含特殊字符，因此该函数无法正确匹配结构。一个例子：
import retxt = 'May enbd company Ltd (Pty) Ltd, formerly known as apple shop Ltd., is a full service firm which is engaged in the sale and servicing of motor vehicles.'re.sub('May enbd company Ltd (Pty) Ltd', 'PC (Pty) Ltd', txt)
这里的问题出在 ( 和 )，但可能存在其他我现在不知道的形式。因此，我想完全忽略这些特殊字符并用我想要的字符串替换它们。在这种情况下，意味着：
'PC (Pty) Ltd, formerly known as apple shop Ltd., is a full-service firm which is engaged in the sale and servicing of motor vehicles.'
英文:
Suppose that I have a list of strings, and I want to substitute different parts of it by re.sub. My problem is that sometimes this substitution contains special characters inside so this function can't properly match the structure. One example:
import retxt = 'May enbd company Ltd (Pty) Ltd, formerly known as apple shop Ltd., is a full service firm which is engaged in the sale and servicing of motor vehicles.'re.sub('May enbd company Ltd (Pty) Ltd', 'PC (Pty) Ltd', txt)
Here the issue is coming from ( and ), but the other forms may happen that I'm not aware of it now. So I want to totally ignore these special characters inside and replace them with my preferred strings. In this case, it means:
'PC (Pty) Ltd, formerly known as apple shop Ltd., is a full-service firm which is engaged in the sale and servicing of motor vehicles.'

If no special functionality of regular expressions is needed, this can be done easier with the str.replace method:
txt = 'May enbd company Ltd (Pty) Ltd, formerly known as apple shop Ltd., is a full service firm which is engaged in the sale and servicing of motor vehicles.'result = txt.replace('May enbd company Ltd (Pty) Ltd', 'PC (Pty) Ltd')
