This looks like a cheatsheet for writing a hard-to-read Python script. I don't know who gets karmic brownie points for a f"{string:>20}" field, but under most normal cases it'd be better to use rjust() directly and not force people to remember Yet Another DSL.
Once a reader could be reasonably expected to consult reference material while working out what a print() is doing something has gone wrong. This is the programmer equivalent of wearing too much makeup.

I think f-strings have become the thing they were trying to replace and they are now more complicated than the old % interpolation.
I still like f-strings and use them a lot but if you look at the cheat sheet, they are no longer simple.

Most of the formatting options in the cheat sheet have always been available with f-strings. They are part of the Format Specification Mini Language (https://docs.python.org/3/library/string.html#format-specifi...) and both string.format and f-strings use the same spec. f-strings have some additional capabilities like inline expressions and debugging/logging with `=`.

Ah, these are great! f-strings are so powerful, but I can never remember the arcane little syntax. Definitely bookmarking this.
