Does Python have something like anonymous inner classes of Java?

Question

In Java you can define a new class inline using anonymous inner classes. This is useful when you need to rewrite only a single method of the class.

Suppose that you

Answer 1

Python probably has better ways to solve your problem. If you could provide more specific details of what you want to do it would help.

For example, if you need to change the method being called in a specific point in code, you can do this by passing the function as a parameter (functions are first class objects in python, you can pass them to functions, etc). You can also create anonymous lambda functions (but they're restricted to a single expression).

Also, since python is very dynamic, you can change methods of an object after it's been created object.method1 = alternative_impl1, although it's actually a bit more complicated, see gnud's answer
