The removal of spaces around keyword arguments is per the PEP8 style guide. There is no point arguing with the style guide. It is there to end discussions. I also do not agree with everything in the style guide. But I keep that to myself. Because a single universal (but flawed) style guides >> competing style guides >> complete anarchy
That I think it's wrong and ugly is an entirely different point.
PEP 8 specifically says it it not universal:
> Many projects have their own coding style guidelines. In the event of any conflicts, such project-specific guides take precedence for that project. ...
> However, know when to be inconsistent – sometimes style guide recommendations just aren’t applicable. When in doubt, use your best judgment. ...
> Some other good reasons to ignore a particular guideline:
> When applying the guideline would make the code less readable, even for someone who is used to reading code that follows this PEP.
I think always omitting spaces there makes it less readable, even for someone who is used to reading PEP 8.
That makes me more compliant to PEP 8 than black. ;)
