Python 3.14 Preview: Template Strings (T-Strings)
Python 3.14’s t-strings allow you to intercept and transform input values before assembling them into a final representation. Unlike f-strings, which produce a str object, t-strings resolve to a Template instance, allowing you to safely process and customize dynamic content.
One of the key benefits of t-strings is their ability to help prevent security vulnerabilities like SQL injection and XSS attacks. They’re also valuable in other fields that rely on string templates, such as structured logging.
By the end of this tutorial, you’ll understand that:
- Python t-strings are a generalization of f-strings, designed to safely handle and process input values.
- The main components of a t-string include static string parts and interpolations, which are accessible through the
Templateclass.
