Python 拆分带有多个分隔符的字符串并找到使用的分隔符 [英] Python split a string w/ multiple delimiter and find the delimiter used

问题描述

如何使用多个分隔符拆分字符串，并找出使用哪个分隔符来拆分 maxsplit 为 1 的字符串.

How to split string with multiple delimiters and find out which delimiter was used to split the string with a maxsplit of 1.

import re

string ="someText:someValue~"
re.split(":|~",string,1)

返回['someText', 'someValue~'].在这种情况下，:"是分割字符串的分隔符.

returns ['someText', 'someValue~']. In this case ":" was the delimiter to split the string.

如果字符串是string ="someText~someValue:"，那么"~"将作为分割字符串的分隔符

If string is string ="someText~someValue:", then "~" will be delimiter to split the string

有没有办法找出使用了哪个分隔符并将其存储在变量中.

Is there a way to find out which delimitor was used and store that in a variable.

PS:someText 和 someValue 可能包含特殊字符，在 split 中不使用.例如:some-Text、some_Text、some$Text

PS: someText and someValue may contain special chars, that are not used in split. Eg: some-Text, some_Text, some$Text

推荐答案

string ="someText:someValue~"
print re.split("(:|~)",string,1)

如果你放入group，它会出现在返回的列表中.你可以从列表的1索引中找到它.

If you put in group,it will appear in the list returned.You can find it from 1 index of list.
