通过多个分隔符分割字符串，忽略重复的分隔符

Question

I'm trying to parse a string that has multiple delimiters which may be repeating.我正在尝试解析具有多个可能重复的分隔符的字符串。

Input string: "-abc,-def,ghi-jkl,mno"输入字符串：“-abc,-def,ghi-jkl,mno”

Expected return: ["abc", "def", "ghi", "jkl", "mno"]预期回报：["abc", "def", "ghi", "jkl", "mno"]

I've tried我试过了

re.split(",|-", string)

But the return is:但回报是：

['', 'abc', '', 'def', 'ghi', 'jkl', 'mno']

Answer 1

Use re.findall :使用re.findall ：

re.findall(r'[^-,]+', string)

See proof查看证明

Python code:蟒蛇代码：

import re
regex = r"[^,-]+"
string = "-abc,-def,ghi-jkl,mno"
print(re.findall(regex, string))

Result: ['abc', 'def', 'ghi', 'jkl', 'mno']结果： ['abc', 'def', 'ghi', 'jkl', 'mno']

Answer 2

You can filter the result like this您可以像这样过滤结果

>>> list(filter(len, re.split(r"[,|-]+", s)))
['abc', 'def', 'ghi', 'jkl', 'mno']
