decorators

Is python interpreted or compiled? Knowing the nuances of the answer will help us build meta code using AST manipulation at runtime. I'll show you how to construct a decorator that can introspect in the local variables without tracing tricks!

Here I will discuss how to use the inspect module and the sys.trace to introspect in a python method using a decorator. With that, we can create a lot cool things like mathematical validation for our arguments, a report generator or any other kind of introspection.
