Good advice. I've got one to add: #x and y are dictionaries z = dict(x.items() + y.items()) It merges two dictionaries, giving precedence to the second (in Python 2 - Python 3 is a bit more nasty: http://stackoverflow.com/questions/38987/how-can-i-merge-union-two-python-dictionaries-in-a-single-expression http://stackoverflow.com/questions/38987/how-can-i-merge-uni...).

Yeah, I like: z=dict(x) z.update(y) It's clear and concise, and it's obvious which one gets precedence, even if it's two lines.

  I tend to be partial towards z = dict(x, **y) if the keys of y are compatible with unpacking.
