I think most people who have tried f-strings have found them handy. Could we transition to making default string literal into an f-string? I think there is a smooth migration path.
f-strings without embedded expressions already compile to the same bytecode as normal string literals. I.e. no overhead. The issue will be literal strings that contain the f-string format characters. We could add a future import, e.g. from __future__ import fstring_literals that would make all literal strings in the module into f-strings. In some future release, we could warn about literal strings in modules without the future import that contain f-string format characters. Eventually, we can change the default. To make migration easier, we can provide a source-to-source translation tool. It is quite simple to do that using the tokenizer module. _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
