properly aligned can enhance readability.

You will find lots of examples. It should be easy to conclude the
comments are more readable if aligned. In fact I'd say the code will be
unreadable if the comment are not aligned. Yet this format require the
same effort to keep neat and tidy and can introduce diff in source code
history some of you object to.
It is very helpful to keep columns aligned when you define a large block
This is a direct violation of PEP-8. But this is so much nicer to scan
the code to do a reverse lookup.
Since PEP-8 does not cover dictionary literals, you tend to find lot

value in this format to apply the extra effort to align them.
I guess I have make justification for this style and I encourage your
judgement rather than feeling compel by a style guide. And get a good
editor. It is not only helpful in writing code. Sometimes you find CSV
