On most systems such modules may be dynamically loaded. Python is also adaptable as an extension language for existing applications. See the internal documentation for hints. Documentation for installed Python modules and packages can be viewed by running the pydoc program. COMMAND LINE OPTIONS -B ...
In both cases, you’re changing the definition of a class dynamically.Writing a class decorator is very similar to writing a function decorator. The only difference is that the decorator will receive a class and not a function as an argument. In fact, all the decorators that you saw above...
