this code gets different check result each time:

def checkio(wordsset): wordslist = [p[::-1] for p in wordsset] for i in range(len(wordslist)): for j in range(i+1, len(wordslist)): try: if not wordslist[i].index(wordslist[j]) or not wordslist[j].index(words_list[i]): return True except: continue return False

for example:

Example: False AssertionError: helLO <module>, 17

Example: True AssertionError: duck to walk <module>, 19

Example: True Done! Time to check!

What's going on?
