  A tool for refurbishing and modernizing Python codebases (by dosisod)

Thank you! I have found that pattern matching has made this project a whole lot easier.

One of the other cool features about this project is how the check() functions are loaded based off the type of the node argument:

This also supports type unions, so you can register your check for binary and unary expressions by typing node as `BinaryExpr | UnaryExpr`.

  Optional static typing for Python

  

The reason I didn't just create a pylint/flake8/mypy plugin is because they all use a very specific methodology, whereas I wanted the freedom to architect it the way I wanted. Also, I really needed good type information, which is why I used mypy[0] as the AST parser/type checker.
