Feature or enhancement f-string.Tagged template literals , and it is a powerful feature.
Pitch
It has similar functionality to f-string, but allows the value to be passed through a specific function before embedding, or to be reformatted for the entire resulting string.lit , which is achieved through tagged literals rather than jsx.
Have we ever talked about introducing tagged literals?

**Feature or enhancement**
Thanks for such a great language and ecosystems! And… I love Python's `f-string`.
I zapped some website, Javascript has *Tagged template literals*, and it is a powerful feature.
- https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals#tagged_templates
- https://wesbos.com/tagged-template-literals
**Pitch**
It has similar functionality to f-string, but allows the value to be passed through a specific function before embedding, or to be reformatted for the entire resulting string.
This functionality is also used in a javascript project called [lit](https://lit.dev/), which is achieved through tagged literals rather than jsx.
Have we ever talked about introducing tagged literals?
I would really like to use this in Python, and I would like to see this functionality used in Python.

@jimbaker has been talking about a feature like this for a while now, but I don’t think he’s written up a PEP for it yet.
I think some related previous discussions can be found by searching for “PEP 501”:

There’s also current work by Jim Baker and Ryan Morshead (with a prototype implementation by myself) towards a PEP that will introduce “tag strings” (tentative name). GitHub - jimbaker/tagstr: This repo contains an issue tracker, examples, and early work related to PEP 999: Tag Strings
If you want to help I recommend reading through the tracker there.
