Test if collections.Mapping is equal to other mapping, or dict

Question

I have written a custom mapping class that inherits from collections.Mapping. Is there an easy way to test if an instance's data is equal to another mapping object, e.g. dict?

Sure. Write __eq__ and __ne__ methods that perform this comparison.

I was hoping there are generic implementation of such methods for mappings that can be reused. – Gary van der Merwe Mar 28 '12 at 15:50
If you derive from `dict` you get comparisons to `dict` for free, but I assumed there was some reason you didn't do that. – kindall Mar 28 '12 at 16:46
