While f-strings in class scope could theoretically be valid docstrings a
lot of the time, the equivalent situation for function docstrings is much
less positive. A function like this the one below obviously problematic,
since the f-string value is not a compile-time constant:
def foo(x): f"is this a docstring? x is {x}"
I'm pretty sure f-strings cannot be used as docstrings in other contexts
because of how broken they'd be in functions.
