Remove empty strings from a list of strings

Question

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

My idea looks like this:

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

Is there any more pythonic way to do this?

Answer 1

I would use filter:

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

str_list = list(filter(None, str_list))
