[Python-Dev] f-strings in the grammar

2021-09-20 Thread Pablo Galindo Salgado
Hi, I have started a project to move the parsing off-strings to the parser and the grammar. Appart from some maintenance improvements (we can drop a considerable amount of hand-written code), there are some interesting things we **could** (emphasis on could) get out of this and I wanted to discuss

I agree it's useful info :) I went ahead and made a PR [1]. In my PR, I simply linked to the Format Specification Mini Language[2] from f-strings documentation[3]. Not sure about updating PEP 498 at this point.. [1] https://github.com/python/cpython/pull/4888 [2] https://docs.python.org/3.6/lib
