py_metaprogramming

Inspired by David Beazley'S tutorial Python 3 Metaprogramming presented at PyCon'13, March 14, 2013. Santa Clara, California.

Considerations

(Class) Decorator vs Metaclass:

• How many functionalities will the Metaclass have?
• Propagation due to inheritance
• decorator to fulfill specialized needs

Use Case

Debug

Problem

While debugging, print or logging function everywhere.

Solution

Use decorator to debug func and class decorator to debug all instance method. Example Link

Signature

Problem

Boilerplate code to assign attribute while init a class.

Solution

Use Signature from the standard library inspect to build signature for function. Example Link
