mypy: Discusses the limitations of type aliases versus NewType for preventing type confusion, the inability to use NewType with certain operations, and more.🔍Featured Study: Formalising Stateful Behaviour Trees for Advanced System Verification💥In the paper, "Formalising Stateful Behaviour Trees,"...
Fortunately, you can take a shortcut by automating most of the hard work by employing tools like the mypy compiler (mypyc) or a code generator like Cython. The latter gives you fine-grain control over the GIL, so you’ll read about it now....
Type hinters like mypy will raise an error when it detects mistakes like this:error: Signature of "get" incompatible with supertype "View" <string>:36: note: Superclass: <string>:36: note: def get(self, request: Any) -> Response <string>:36: note: Subclass: <string>:36: note: ...
