Python Pyupgrade Syntax Modernizer

To automatically upgrade Python syntax, you can run pyupgrade on your files and configure a minimum target Python version (3.6+ to 3.14+). This applies safe, non-destructive syntax transformations appropriate for your specified runtime.

Migrating a mixed Python 2 and 3 codebase to modern syntax is best handled by batch processing with pyupgrade. It automatically removes deprecated constructs like class Foo(object), ensuring your codebase cleanly supports current Python runtimes.

Yes, you can integrate automated Python code refactoring into a pre-commit hook. Pyupgrade is designed for easy integration into pre-commit hooks and CI workflows, enforcing modern syntax and updated type hints across your repository automatically.

Yes, pyupgrade supports updating type hints during Python migrations. It provides comprehensive coverage that modernizes strings, imports, class definitions, and type hints while applying conservative changes designed to preserve original behavior.

Pyupgrade syntax transformations are safe for existing codebases because they are explicitly designed as conservative, non-destructive changes. They modernize common Python constructs while preserving the original runtime behavior of your code.
