How to create a loop that deletes empty strings within a list, whilst keeping the strings with conte-CodePudding

I have a list named player_home_run, and the way that my program works is that sometimes, empty string is entered to it, and sometimes, words and other strings are entered into it. After a loop, the string sometimes looks like this:

['', '', '', '', 'Perez', '', '', '', 'Guerrero']

I would like to make a small loop that would delete all the empty spaces and leave me with only the names in the string. The length of the string should be the same as the # of names.

Should look like this:

['Perez', 'Guerrero']

I want to avoid using filter.

Edit: I figured out the ans right after posting this question.

Here's the code

            if hit == True:
            print(player_home_run, '# of homeruns')
            run_calc = True
            while run_calc == True:
                if '' in player_home_run:
                    player_home_run.remove('')
                    ttl_runs = player_home_run
                else:
                    print('no more whitespace.')
                    print(ttl_runs, ' ttl runs')
                    run_calc = False

You could do a comprehension, like:

player_home_run = [item for item in player_home_run if item != ""]

If you want to do a loop, then simply qualifying each iteration with an if statement will suffice. Here is an example:

listA = ['', '', '', '', 'Perez', '', '', '', 'Guerrero']
listB = []
for item in listA:
    if item != "":
        listB.append(item)
listA = listB
print listA

Here is the output for this script:

['Perez', 'Guerrero']
