拆分字母数字字符串

Question

I have several strings that look like

"Abcde fgh 123,456"

I want to split it as

["Abcde fgh", "123,456"]

I tried

string = "Abcde fgh 123,456"
re.split(r'(\d+)', string)

But this gives

["Abcde fgh", "123", "," "456"]

Answer 1

You get that result because you use a capturing group with split which will also return the captured text.

You could use a positive lookahead instead. (?=\\d) would work, but to be more precise for your example data you could also use:

(?<!\\d)\\s+(?=\\d+,\\d+)

Regex demo

import re
string = "Abcde fgh 123,456"
print(re.split(r'(?<!\d)\s+(?=\d+,\d+)', string))
