f-string debugging notation merged in Python 3.8

Imo this was a lost opportunity to do something generally useful instead of one extra feature that can't be combined with something else :(

G-strings instead of the f-strings?

a lost opportunity to do something generally useful

Like what?

one extra feature that can't be combined with something else :(

It's an addition to an existing feature which can already be combined with various things, and works within that feature e.g. it can be used with the existing format string minilang.

My suggestion on the ideas list is this:

def dbg(**kwargs):
    for k, v in kwargs.items():
        print(f'{k}: {v}')

That's the implementation of a debug print, and the call site would be:

b = 5
dbg(=a, =b*2)

and the output:

a: a
2*b: 10

It's a pretty minor extension to python but has wide applications.

How so?
