[ANSWERED] F-string or .format()?

What would be a more efficient way to declare variables?

The f-string is a relatively new feature (python 3.6) so if you have to use earlier versions for any reason, or be backwards compatible, then you can't use them. But generally I prefer f-string for its brevity :)

Here is a link to a (hopefully) tutorial about the different kinds of formatting strings: https://realpython.com/JUMP_LINK__&&__python__&&__JUMP_LINK-string-formatting/ Here is an other link that covers a lot of aspects about string formatting: https://stackoverflow.com/questions/5082452/string-formatting-vs-format

I think, internally it should be the same: According to your specifications, a new string is created. So it's probably a matter of taste which of these you choose: x = 1.23456 a = f'x: {x:.2f}' b = 'x: {:.2f}'.format(x) c = 'x: '+format(x, '.2f') d = 'x: %.2f'%x print(a, b, c, d)
