dicts.add

dicts.add(dictionaries, kwargs)

Returns a new dict that has all the entries of the given dictionaries.

If the same key is present in more than one of the input dictionaries, the last of them in the argument list overrides any earlier ones.

This function is designed to take zero or one arguments as well as multiple dictionaries, so that it follows arithmetic identities and callers can avoid special cases for their inputs: the sum of zero dictionaries is the empty dictionary, and the sum of a single dictionary is a copy of itself.

Parameters

dictionaries	optional. Zero or more dictionaries to be added.
kwargs	optional. Additional dictionary passed as keyword args.
