Track changes to lists and dictionaries in python?

Question

I have a class where the instances of this class needs to track the changes to its attributes.

Example: obj.att = 2 would be something that\'s easily tr

Answer 1

Instead of monkey patching, you can create a proxy class:

• Make a proxy class that inherit from dict/list/set whatever
• Intercept attribute setting, and if the value is a dict/list/set, wrap it into the proxy class
• In proxy class __getattribute__, make sure the method is called on the wrapped type, but take care of tracking before doing so.

Pro:

• no class alteration

Con:

• you are limited to a number of types you know and expect
