Add f-string support ? about asteval HOT 4 CLOSED

@whg517 no, it does not, at least not at the moment. Interpreting and evaluating f strings look slightly complicated to me, as one would have to implement all the formatting options.

If this was a priority for someone who was willing to add it to asteval, I would be willing to guide and help, but it is not a priority for me on my own.

@newville Ok, I see. I'll choose another way to use it. thank you.

Perhaps the f-yeah package be leveraged to provide this (or something similar): https://github.com/ucodery/fyeah

@moloney Thanks for the link and suggestion. I think (but am not certain) that library probably exposes Python's eval(). I like the idea of this library, but I think that the use of eval() with f-strings would need to be taken into consideration and probably be "opt-in".

Another consideration: the current complete list of dependencies for asteval is: importlib_metadata ; python_version < "3.8". I'm not adamantly opposed to adding dependencies, but I think that ought to be done carefully and with long-term support in mind. I could be wrong, but fyeah looks a bit new/small/proof-of-concept. Again, that is not "No", just "there are things to consider.
