Python多分隔符号拆分字符串

如下代码,实现python多个分隔符拆分字符串。

def tsplit(string, delimiters):
    """Behaves str.split but supports multiple delimiters."""

    delimiters = tuple(delimiters)
    stack = [string,]

    for delimiter in delimiters:
        for i, substring in enumerate(stack):
            substack = substring.split(delimiter)
            stack.pop(i)
            for j, _substring in enumerate(substack):
                stack.insert(i+j, _substring)

    return stack

很多时候我们需要用多个分隔符拆分字符串,例如拆分标签时,既要用中文的分号,也要用到英文的分号。

如下是使用方法:

>>> s = 'thing1,thing2/thing3-thing4'
>>> tsplit(s, (',', '/', '-'))
['thing1', 'thing2', 'thing3', 'thing4']
