That's interesting, for me both 3.9 and 3.10 show the f-string more than 5x faster. This is just timeit on f'{myvar}' vs ''.join((myvar,)) so it may not be the most nuanced comparison for a class property. Probably unsurprisingly having myvar be precomputed as the single tuple also gives speedups, around 45% for me. So if just speed is wanted maybe inject the tuple pre-constructed. ~ Jeremiah On Wed, Dec 21, 2022 at 1:19 AM Steven D'Aprano <steve@pearwood.info> wrote:

By my testing, on Python 3.10, this is slightly faster still:
@property def data(self): return "".join((self,))
That's about 14% faster than the f-string version.
