从字符串列表中删除空字符串 [英] Remove empty strings from a list of strings

问题描述

我想从python中的字符串列表中删除所有空字符串.

I want to remove all empty strings from a list of strings in python.

我的想法如下:

while '' in str_list:
    str_list.remove('')

还有其他pythonic方式可以做到这一点吗?

Is there any more pythonic way to do this?

推荐答案

我会使用> c0> :

str_list = filter(None, str_list)
str_list = filter(bool, str_list)
str_list = filter(len, str_list)
str_list = filter(lambda item: item, str_list)

Python 3从filter返回一个迭代器，因此应包装在对list()

Python 3 returns an iterator from filter, so should be wrapped in a call to list()

str_list = list(filter(None, str_list))
