i'm back to f-strings, again

[Skaperen]

yeah, the file will have the same kind of thing as you see between quotes of an f-string literal but it would not be a literal. i cannot remember where i read this but i read that there was a way to pass such a string to some method called format that would format it in the specified/given context. it have looked at the description of the builtin format() but it does not seem to have a way to execute a snippet (stuff between {}) that is executable code. so i can put a var name in there but not an expression.

i can do what i want in Bash using the eval command. i just need to put '$' in front of the { for each snippet and make it run in a way that it captures the evaluation into a string. i have done the bash thing before.

but i now want to do this in Python.
