python – “ValueError : list.remove(x): x not in list” when x is in list

I have tried many possible solutions but none of them worked. My code is a simple word counter that counts the frequency of words in song lyrics. Since short words should’t be counted I wrote this code. My word and their count lists look like this.

 goodwords=("a", "my", "the", "I", "long", "up", "on") 
 count=(26, 16, 16, 15, 12, 11, 11 )

So I wrote this code to filter out short words.

for word in goodwords:
if len(word)<3:


Python throws me this error:

ValueError: list.remove(x): x not in list

Even when I try to assign the index of the word to an int the same error is shown.
