I don't understand why you fully ignore literally the FIRST example I
gave in my original post and angrily claim that you solution works
when it does not:
x = { "y": "z" }
s = "-> {x['y']}"
print(s.format(x = x))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: "'y'"
This. Does. Not. Work.
It's because "you're holding it wrong!". Notice the error message; it
says that the key 'y' does not exist.
Ah, that is neat! I didn't know that. Thanks for the info.
In my case, I do also however want to have some functionality that
actually does math or even calls functions. That would be possible with
templates or f-strings, but not format:
x = { "t": 12345 }
s = "{x['t'] // 60:02d}:{x['t'] % 60:02d}"
print(s.format(x = x))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: "'t'"
and
s = "{x[t] // 60:02d}:{x[t] % 60:02d}"
print(s.format(x = x))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: Only '.' or '[' may follow ']' in format field specifier
but of course:
print(f"{x['t'] // 60:02d}:{x['t'] % 60:02d}")

Best,
