@Carlosbogo Awesome! Now - there are flake8 formatting errors, here. To fix anything with lines that are too long simply add a ' # noqa' (without the quotes) to the end of the associated line.

This would ideally be solved by #1644 anyways.

@Carlosbogo We are so close. There are two flake8 errors left:

./redis/commands/core.py:2187:1: W293 blank line contains whitespace
./redis/commands/core.py:2195:1: W293 blank line contains whitespace

If you can eliminate those (and other flakes), I'll pull this into whichever release this lines up with, 4.0.2 or 4.1.0.

If it helps - you can test locally prior to pushing by:

1. pip install flake8 (I'm assuming you have a virtualenv) or pip install --user flake8
2. Run flake8 in your terminal

Thank you for the advice, that will definitely help a lot in the future!

Well this is just awesome. Thank you so much @Carlosbogo for making these changes. I'm going to add it into the upcoming (4.0.2) release. So that we can roll this out tomorrow. 👏
