WebCython determines whether a variable belongs to a local scope, the module scope, or the built-in scope completely statically. As with Python, assigning to a variable which is not otherwise declared implicitly declares it to be a Python variable residing in the scope where it is assigned. Unlike WebCython is a Python compiler. This means that it can compile normal Python code without changes (with a few obvious exceptions of some as-yet unsupported language features, see Cython limitations).However, for performance critical code, it is often helpful to add static type declarations, as they will allow Cython to step out of the dynamic nature of the …
