python - 在 Python 中将字符串拆分为列表(但不分隔相邻数字)

Question

例如，我有:

string = "123ab4 5"

我希望能够得到以下列表:

["123","ab","4","5"]

而不是 list(string) 给我:

["1","2","3","a","b","4"," ","5"]

Answer 1

查找一个或多个相邻数字 (\d+)，或者如果失败则查找非数字、非空格字符 ([^\d\s]+ ).

>>> string = '123ab4 5'
>>> import re
>>> re.findall('\d+|[^\d\s]+', string)
['123', 'ab', '4', '5']

如果你不想把字母连在一起，试试这个:

>>> re.findall('\d+|\S', string)
['123', 'a', 'b', '4', '5']
