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

For a list with a combination of spaces and empty values, use simple list comprehension -

>>> s = ['I', 'am', 'a', '', 'great', ' ', '', '  ', 'person', '!!', 'Do', 'you', 'think', 'its', 'a', '', 'a', '', 'joke', '', ' ', '', '?', '', '', '', '?']

So, you can see, this list has a combination of spaces and null elements. Using the snippet -

>>> d = [x for x in s if x.strip()]
>>> d
>>> d = ['I', 'am', 'a', 'great', 'person', '!!', 'Do', 'you', 'think', 'its', 'a', 'a', 'joke', '?', '?']
