black https://pypi.org/project/black/ is the Uncompromising Code Formatter. You can install it, run black and it will format the code properly. How about using it for the project in order to make sure style is consistent?

Hi Diego, the code was already black formatted.

The inconsistency was because I initially forced 80 chars line length in my IDE. Then, I reverted it to 88 as suggested in black documentation but forgot to run black project-wise.

Now code formatting should be consistent.
