PEP 750 introduces Template Strings, or t-strings, into Python, building on lessons learned from f-strings and the earlier PEP 501. T-strings allow for deferred evaluation of expressions, a significant limitation noted in f-strings, where values are interpolated immediately. Users have expressed excitement about the potential for this new feature to improve string handling, with comparisons to JavaScript’s tagged template literals for better safety and functionality. However, there are concerns about increasing language complexity and maintaining readability given the new syntax. Alternatives like `str.format` are noted as still being optimal for many users. There are mixed feelings about the need for t-strings, with some expressing that existing methods suffice and a desire for more impactful updates in Python's development. There are calls for features enhancing functions like sanitization and rendering to be included as official methods, rather than requiring users to implement these manually.
