Python 3.14's Game Changer: Template Strings (t-strings) for Safer String Formatting

Python 3.14, shipping in late 2025, introduces template strings (t-strings), a significant enhancement to string formatting. Addressing the security risks of f-strings when handling user input (like SQL injection and XSS), t-strings separate string formatting from content. This allows for safe escaping before formatting, enhancing flexibility for complex tasks such as generating secure HTML. Developers access the string parts and values via .strings and .values properties, enabling custom formatting. Iteration is also supported for easier processing. This boosts Python's security and expands string manipulation capabilities.
