python - python在字符串中拆分数字

Question

我想知道以以下方式分隔字符串中数字的最简单方法（可能是正则表达式）是什么。示例："abc12de34f5" 到：["abc", "12", "de", "34", "f", "5"]

但是，如果字符串中有连接标记，请以这种方式分隔：示例："abc1,2de3.4f5" to：["abc", "1,2", "de", "3.4", "f", "5"]

感谢您的任何建议和意见

Answer 1

>>> import re
>>> s = "abc12de34f5"
>>> re.findall(r'[\d\W]+|[a-zA-Z]+', s)
['abc', '12', 'de', '34', 'f', '5']
>>> t = "abc1,2de3.4f5"
>>> re.findall(r'[\d\W]+|[a-zA-Z]+', t)
['abc', '1,2', 'de', '3.4', 'f', '5']

Answer 2

使用 itertools.groupby 的非正则表达式解决方案

>>> st = "abc1,2de3.4f5"
>>> [''.join(v) for _, v in groupby(st,key = str.isalpha)]
['abc', '1,2', 'de', '3.4', 'f', '5']
>>> st = "abc12de34f5"
>>> [''.join(v) for _, v in groupby(st,key = str.isalpha)]
['abc', '12', 'de', '34', 'f', '5']
