Hi @yangyangxcf. Unfortunately, the ast.c module has changed recently and all the functionality has been ported to some new files under the Parser directory. Could you update your PR for the new layout? If you don't have time, I could do it for you if you wish.

Ping, @yangyangxcf, @pablogsal?

This PR still needs to be rebased as per #19398 (comment). As I mentioned, I am fine to take it over if @yangyangxcf is ok with that

Let's give this another couple of weeks then, @pablogsal?

I believe this was fixed by #27729.

The reported issues seem similar to what is fixed there. Note that on Python 3.10 this now works as expected:

>>> ast.parse("f'{a}'").body[0].value.values[0].value.col_offset
3
>>> ast.parse("f'{a:b}'").body[0].value.values[0].value.col_offset
3

The other issue in the original report is resolved as well.

Edit: @ericvsmith Gentle ping since you closed the bpo and might want to close this PR as well 😄

@DanielNoord :Thanks for the reminder!
