使用正则表达式删除特定单词之间的单词

Question

My data contains something like these:

→ muching :酋長在這個距離的時候，北部山區都超過大豪雨標準了

推aitt :台東恆春間登陸不代表北台不會有強風.

→ teras: 7／7

I want my data to look like these:

酋長在這個距離的時候，北部山區都超過大豪雨標準了

台東恆春間登陸不代表北台不會有強風.

 7／7

I already tried some regex re.sub(r'^推:$', '', x) but I'm pretty sure this way is wrong.

does regex work with Chinese characters or → symbols?

Answer 1

You can try something like this, it will remove everything that starts in a line before the : and → does work with Chinese characters:

import re

txt = """
→ muching :酋長在這個距離的時候，北部山區都超過大豪雨標準了

推aitt :台東恆春間登陸不代表北台不會有強風.

→ teras: 7／7

"""

pattern = r'^.*:'
parsed_txt = re.sub(pattern, '', txt, flags=re.MULTILINE)

print(parsed_txt)
>>>"
酋長在這個距離的時候，北部山區都超過大豪雨標準了

台東恆春間登陸不代表北台不會有強風.

 7／7"
