In Programming Python, Mark Lutz mentions the term mixin. I am from a C/C++/C# background and I have not heard the term before. What is a mixin?
What’s the difference between:
Say I have a multiple inheritance scenario:
I have code like this:
I’m running Python 2.5, so this question may not apply to Python 3. When you make a diamond class hierarchy using multiple inheritance and create an object of the derived-most class, Python does the Right Thing (TM). It calls the constructor for the derived-most class, then its parent classes as listed from left to right, then the grandparent. I’m familiar with Python’s MRO; that’s not my question. I’m curious how the object returned from super actually manages to communicate to calls of super in the parent classes the correct order. Consider this example code:
Consider the following snippet of python code
I need a double inheritance for a class.
I tried several syntaxes but I don’t understand the concept of metaclass.
It’s often stated that super should be avoided in Python 2. I’ve found in my use of super in Python 2 that it never acts the way I expect unless I provide all arguments such as the example: super(ThisClass, self).some_func(*args, **kwargs) It seems to me this defeats the purpose of using super(), it’s neither more … Read more
