Hi Evan,
f-strings support a version of this. If you put an equals sign at the
end of the expression in your f-string (possibly with white space) then
the f-string will include both the expression itself and its value in
the result:
>>> a = 12; b = 13
>>> f'{a == b}'
'False'
Are you familiar with the f-string self-documentation operator in python
3.8?
https://docs.python.org/3/whatsnew/3.8.html#f-strings-support-for-self-documenting-expressions-and-debugging
With it you can say:
print(f"{a==b=}")

It would be nice to add the following syntax sugar in Python "Print and Eval"
like `ptev a == b` It is same as `statement = "a == b"; print(f"{statement} ?
{eval(statement)}")`.
It would super nice for debugging and other research project.

This proposal is not about saving a few characters. We could
I definitely agree with that sentiment, with beginners I don't even talk
about function defaults at first, and when I do, it's when we have already
have a talk about mutables so I can just say that you almost never want a
mutable default but rather use None as a sentinel. It's not that hard and
it

Ah yes, I forgot about class namespaces. I was thinking about
deliberately wonky namespaces where the ns dict has a __missing__
method or something, but inside a class, "b = b" actually has a

Be careful what you say: there are some technicalities. If you mean

I don't want to live in a universe where this could be anything
other than a no-op in Python.
