merging two dictionaries

[nilamo]

You can always roll your own.  Just because it isn't in dict doesn't mean you can't use things that waddle and quack like dicts...

class Wrapper(dict):
    def __add__(self, other):
        final = {}
        for obj in [self, other]:
            final.update(obj)
        return final

a = Wrapper({1: 2, 3: 4})
b = Wrapper({1: 3, 5: 6})
print(a+b)
# {1: 3, 3: 4, 5: 6}
