Remove empty strings from a list of strings

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?

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))
