python - 在字符串拆分期间删除空条目

Question

目前我使用这个辅助函数来删除空条目。

有内置方法吗？

def getNonEmptyList(str, splitSym):
    lst=str.split(splitSym)

    lst1=[]
    for entry in lst:
        if entry.strip() !='':
            lst1.append(entry)

    return lst1

Answer 1

str.split(sep=None, maxsplit=-1)

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace.

例如:

>>> '1 2 3'.split()
['1', '2', '3']
>>> '1 2 3'.split(maxsplit=1)
['1', '2 3']
>>> '   1   2   3   '.split()
['1', '2', '3']
