Duh! Am I the only one who feels stupid not thinking of this?
Although of course it won't work if the string already contains triple
double quotes.
I believe this could be got round with some ingenuity (having the effify
function parse the string and replace genuine (not embedded in
single-quotes) triple double quotes with triple single quotes, though
there are some complications).
And the effify function can't be put in its own module unless it can be
passed the globals and/or locals dictionaries as needed for eval to
use. Something like this:
def effify(non_f_str, glob=None, loc=None):
return eval(f'f"""{non_f_str}"""',
glob if glob is not None else globals(),
loc if loc is not None else locals())
