Solve the following python programming problem given the following code:
def main() : 
    'Commandline interface for measure pairwise similarities of files' 
    parser = argparse.ArgumentParser (description = 'List pairwise similarities of input documents') 
    parser.add_argument ('doc', nargs = '*', help = 'a document in the comparison list') 
    parser.add_argument ('-f', '--filename_list', nargs = '?', help = 'file containing list of filenames to compare') 
    parser.add_argument ('-u', '--url_list', nargs = '?', help = 'file containing list of urls to compare') 
    args = parser.parse_args () 
    def get_list(input_fname) : 
        list = [] 
        if (input_fname is not None) : 
            try : 
                with open (input_fname) as input_file : 
                    list = [line.strip () for line in input_file.readlines ()] 
except IOError : 
                print (('Sorry, could not open ' + input_fname)) 
return list 
filenames = get_list (args.filename_list) 
    urls = get_list (name_a.url_list) 
    for doc in args.doc : 
        if re.search ('^http://', doc) : 
            urls.append (doc) 
else : 
            filenames.extend (doc) 
if ((len (filenames) + len (urls)) < 2) : 
        raise Error ('Sorry, you must specify at least two documents to compare.') 
print ('Comparing files {}'.format (list (chain (filenames, urls)))) 
    similarities = pairwise_compare (filenames = filenames, urls = urls) 
    for (name_a, name_b, sim) in similarities : 
        print ('sim({0},{1})={2}'.format (name_a, name_b, sim)) 

    
    

    Fix the buggy line: urls = get_list (name_a.url_list)

#Here is Python code to fix the buggy line: urls = get_list (name_a.

urls = get_list (args.url_list)
