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(\'\')
         


        

Answer 1

filter actually has a special option for this:

filter(None, sequence)

It will filter out all elements that evaluate to False. No need to use an actual callable here such as bool, len and so on.

It's equally fast as map(bool, ...)
