Hi @deepang17 - instead of excluding a file, can we change `test_unique_tuples` so the last argument of the function is `uniques` instead of `unique`? Sure, will do that. Thanks @deepang17 , I'll just mark this as draft pending on https://github.com/pandas-dev/pandas/issues/39992#issuecomment-792294708 , will then reopen (depending on what we hear back, you may need to rebase / fix conflicts) Hi @deepang17 - #40310 is in, do you want to rebase and fix up any remaining errors so we can get this in? Hello, @MarcoGorelli I have completed work from my side. If you think that changing from `unique` to `uniques` is not a breaking change then this works fine. You'll also need to change it to `uniques` in
```
    @pytest.mark.parametrize(
        "arr, unique",
```

It's just a variable in a test, so it's not a breaking change

If you could fetch and merge upstream/master and fixup "unique" in `pytest.mark.parametrize` then this should be good to go Ok, will do that. ![image](https://user-images.githubusercontent.com/47976918/110361148-a0a2ad00-8065-11eb-89e1-e5996f7fbbb3.png)

@MarcoGorelli these new files are producing the error.

I'd suggest renaming to `arr` rather than `arrays`, as here there's only one of them (`uniques` in `test_algos.py` is fine as there's many objects there anyway many objects and arguably might have been better named `uniques` from the start) `arr` is used at quite a few places, so it will again create conflicts. Please suggest something else. Thank you. @MarcoGorelli it's ready to be merged. Thank you for your guidance. Hi @deepang17 - can you fetch and merge upstream/master please? Great, at that time some other variables were also used with the name `arr` and one of them produced an error for me hence I thought it will produce an error for all. But now as you have done it, it seems fine. Thanks @deepang17 !
