Python 3.14 has a new feature called the template string, or t-string, type. A t-string superficially resembles an f-string, but it’s designed to do something very different.

For some time now, Python developers have been able to “annotate” names with type information. With Python 3.5, type hints officially became part of the language (see PEP 484).

One of the first concepts you’ll need to familiarize yourself with to that end is how to use strings. In this post, you’ll learn how to create, change, and concatenate strings in Python.
