my code:

Codes removed by mentor as posting any grade function codes is considered against code of conduct. if a mentor wants to look at your codes they will ask you to send the code screenshot by personal DM, until then only post screenshot of error encountered or your expected output or failed submission grader info.

Output is a list of indices

bm25_retrieve(“What are the recent news about GDP?”)

Need help with this error.

Please do not share your code on the forum. That’s not allowed by the Code of Conduct.

I’ll mark this thread as “Unlisted” so the staff or a mentor for the course can still find it.

Others will not be able to see it.

Sure. Thank you very much. I will take care of it next time.

hello @Sudhir_Dudwadkar

That error is actually pointing out clearly that the extra subscript bracket you are using for corpus.index is incorrect. Remove that extra bracket {corpus.index(doc)}, { } this needs to be removed.

The error TypeError: 'int' object is not subscriptable occurs in Python when you try to use indexing {} on an integer
