It might be because your pro_list contains strings so pro_list[counter][1] != False will always be true because you compare a string to a boolean. I think it was supposed to be != '0'.

You do not pass all the tests. You pass some tests, and then time out.

I've seen it in other katas. Just consider it's time out.

Hint: Your solution will give "Automorphic" for 16 - 16 is not automorphic (reread the problem description to see why)

Because there are zeros after the False. Check how your old code worked here: http://www.pythontutor.com/visualize.html#mode=edit with an input like this one: [1, False, 1, 0]

Because remove doesn't distinguish them.
