如何通过重复字符查找和拆分字符串? [英] How to find and split a string by repeated characters?

问题描述

我正在尝试在 python 中将一个字符串拆分为一个列表，并以字符更改分隔.我发现这非常困难，但我确信我想多了，错过了一个可能简单的解决方案.示例:

I am trying to split a string into a list, separated by a change in character, in python. I am finding this very difficult, but am sure that I am over thinking it and missing a probably simple solution. Example:

'abgg22ffeeekkkk1zzabbb'

'abgg22ffeeekkkk1zzabbb'

会变成:

['a', 'b', 'gg', '22', 'ff', 'eee', 'kkkk', '1', 'zz', 'a', 'bbb']

['a', 'b', 'gg', '22', 'ff', 'eee', 'kkkk', '1', 'zz', 'a', 'bbb']

推荐答案

import itertools
[''.join(value) for key, value in itertools.groupby(my_str)]
