[SagiPolaczek]

#141

This is the implementation I came up with. See details of the feature in the attached issue

@SagiPolaczek Thanks for raising this PR! I apologize for not having reviewed this yet, I will jump on this ASAP.

[rohitsanj]

I wonder why CI hasn't been triggered on this PR. Strange.

[rohitsanj]

@SagiPolaczek can you please try pushing an empty commit using git commit --allow-empty -m "Trigger GitHub CI"?

[rohitsanj]

Minor comments.

Also, please add some unit tests to testbook/tests/test_client.py for when skip is: int, str, list[int], [list[str].

Thanks again!

[rohitsanj]

We would also want to accept cell tag(s) as input for the skip argument for users who wouldn't want to concern themselves with knowing which index each cell is at.

Suggested change

	if isinstance(skip, int):
	skip = [skip]
	if isinstance(skip, int) or isinstance(skip, str):
	skip = [skip]
	if all(isinstance(x, str) for x in skip):
	skip = [self._cell_index(tag) for tag in skip]

[rohitsanj]

Suggested change

	Executes all cells besides the ones who were asked to be skipped
	Executes all cells.
	If skip is passed, we will remove those cell(s) from the list of cells to be executed.

@rohitsanj I kinda want this feature so if it's cool with you can I take this across the finish line?

[rohitsanj]

Sure, @rprater! Thanks.

[SagiPolaczek]

Thanks @rohitsanj for taking it and thanks @rohitsanj for maintaining the repo.
