How to remove empty string in a list?

Question

For example I have a sentence

\"He is so .... cool!\"

Then I remove all the punctuation and make it in a list.

[\"He\", \"         


        

Answer 1

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

str_list = list(filter(None, str_list)) # fastest

Answer 2

lst = ["He", "is", "so", "", "cool"]
lst = list(filter(str.strip, lst))

Answer 3

You can filter out empty strings very easily using a list comprehension:

x = ["He", "is", "so", "", "cool"]
x = [str for str in x if str]
>>> ['He', 'is', 'so', 'cool']
