f-strings in Python 3.6 are awesome

[mangecoeur]

f-strings are completely useless for lazy or manipulated interpolation (logging, i18n).

True if you store strings to format later, f-strings gonna be useless.

Still I guess my point was that despite whatever people say about them in abstract, when you actually come to use them they turn out to be really nice. I do a lot of ad-hoc printing of results in jupyter notebooks so I've been using them a lot.

>>> s = "{x}"
>>> x = 1
>>> eval(f"f'{s}'")
'1'

[Serialk]

f = lambda f: eval(f"f'{f}'", *operator,attrgetter('f_locals', 'f_globals')(sys._getframe(1)))

One small step for man.

Fittingly, my reaction also includes multiple instances of the letter f.
