python 2.7 : how to find the index of the first letter of each word in a string

Question

我正在寻找一种在 Python 中检测字符串中每个单词第一个字符的索引的方法:

string = "DAY MONTH      YEAR    THIS   HAS RANDOM   SPACES"

我想找到每个“单词”的位置，所以这个输出将是:

[0, 4, 15, 23...]

有谁知道我如何才能做到这一点？

Answer 1

>>> import re
>>> string = "DAY MONTH      YEAR    THIS   HAS RANDOM   SPACES"
>>> [match.start() for match in re.finditer(r'\b\w', string)]
[0, 4, 15, 23, 30, 34, 43]
