Python’s new t-strings

Personally, this feels like a feature that is too focused on one problem to be a general feature. Python is getting huge. When people ask me if Python is easy and simple to learn I have to say "the basics, yes, but to to learn the whole language... not so much".

I feel like in this sense Go really is interesting by rejecting almost every single feature. Honestly not sure generics were worth it as they add a lot of complexity, and while they are nice, I don't need them very much. The general idea to keep the language at its original focus is the right idea IMO. C++ would be the most extreme case where the language itself barely resembles what it started out as.

Python has always been a batteries-included language, so having a go at templated string interpolation —a feature other languages have had for decades— seems like a strange gripe.

It's far more essential than little utilities like textwrap or goliath packages like Python's bundled tkinter implementation.

What other languages have this feature? I'm not aware of any

Many languages have similar features.

For instance, Python has the % operator that is a template format that allows interpolating values based on a template string with a variety of printf-like features: https://python-reference.readthedocs.io/en/latest/docs/str/f...

Also, Python has the .format method on strings, which is a template format that allows interpolating values based on a template string: https://www.geeksforgeeks.org/python-string-format-method/

As another example, Python has f-strings that are a template format that allows interpolating values based on a template string: https://www.geeksforgeeks.org/formatted-string-literals-f-st...

Also, you can also find languages like Python that have a rich ecosystem of third party templating solutions. These are often intended for things like rendering entire web pages but many of them have relatively simple ways of using their templating functionality in a fairly reasonable amount of code, if you just want to have a template format that allows interpolating values based on a template string.

So, as you can see, many other languages have this feature, as you can tell from all the examples I have shown you here.

(To spell it out for those who may find this too subtle... somehow... I'm not a fan of this simply because Python has gone from "There should be one-- and preferably only one --obvious way to do it." to "there's half-a-dozen ways to do it and if they are all wrong Python 3.x+1 will introduce a seventh" and I'm just not seeing the benefits worth the tradeoffs here.)

I find this a confusing reply. First, you seem to be confusing eager string interpolation with this lazy/deferred templating feature. I'm specifically asking about languages that have the latter. More confusingly, you bring up the language under discussion as an example... if it already had this feature, they wouldn't be adding a new feature.

Then, you bring up 3rd party templating solutions, but this is off topic, as we are talking about language builtins. I am well aware there are many templating solutions to solve text templating in general.

In summary, I'm specifically asking for examples of languages that allow string interpolation with _deferred/lazy_ processing, which is how I understand this feature. It seems there are a few, but it doesn't seem to be terribly common after reading the other comments.
