Python Code Dependency Injection
Project description
A simple Python CDI ( Code Dependency Injection) Library.
The decorators of Python2 define the types and the contexts of the injections. In the Python3 the types are defined with type-hints ( __annotations__ ) and the decorators defines the contexts. The contexts are like the scopes (@Scope) of Java.
