t-strings (or template strings) are an upcoming Python 3.14 feature. They have similar syntax to f-strings (which were introduced in 3.6) except that they provide access to the string and the interpolated values (the bits inside the curly brackets) before they have been combined. Previously, something like

  db.query(f"SELECT * FROM table WHERE id={id};")

would have been vulnerable to the classic "bobby tables" SQL injection but t-strings allow for almost the same syntax (which is quite natural for Python programmers) without incurring a security risk.

If you are curious, t-strings have previously been discussed here (https://news.ycombinator.com/item?id=43748512 and https://news.ycombinator.com/item?id=43647716) and you can read the PEP that proposed their addition to the language (https://peps.python.org/pep-0750/).
