Hmm, is this the best example? The main use case for this feature is for debugging, and there doesn't really seem to be any debugging going on in this example.

Hmm, is this the best example? The main use case for this feature is for debugging, and there doesn't really seem to be any debugging going on in this example.

Maybe something like

bugs = 'roaches'
count = '13'
area = 'living room'
print(f'Debugging: {bugs=} {count=} {area=}')
...

And this tutorial section could possibly also use an example for printing the curly brackets too

... And you can escape curly brackets in f-strings by using two:

...
print(f'Debugging: {{{bugs=} {count=} {area=}}}')
...

The last example you provided is very nice. I would split the example of showing {{ into a separate one so that newbies won't confuse themselves into thinking that {= requires triple braces.

The last example you provided is very nice. I would split the example of showing {{ into a separate one so that newbies won't confuse themselves into thinking that {= requires triple braces.

It is a good example, except I'd make count an integer, not a string. And I'd omit the {{ example entirely, because it's orthogonal to this and covered elsewhere.
