I thought about splitlines but it does not give the same result: print(b'abc\r\r\ndef'.splitlines()) # [b'abc', b'', b'def'] Even with keepends=True , it's

问题 This question already has an answer here : Split regex to extract Strings of contiguous characters (1 answer) Closed 5 years ago . I'm new to using regular expressions, but I think that in an instance like this using them would be the quickest and most ellegant way. I have a binary string, and I need to split it into groups that only contain consecutive zeros or ones, for example: 110001 would be split into 11 000 1 I just can't figure it out, this is my current code, thanks: class Solution {

问题 I need to split a string by a charcter plus a wildcard character: text1 = "CompanyA-XYZ-257999_31.12.2000" text2 = "CompanyB-XYZ-057999_31.12.2000" I want to split that string at the position [-2] or [-0], so right after XYZ. Since I have two "-", I can not simply split by that character. In fact i would like to have a split in the form [-AnyNumber], where AnyNumber should be a wildcard for an integer. 回答1: You don't need a regex, you can split from the right using str.rsplit setting maxsplit
