'|' is the set union operation, roughly equivalent to the set.union method. Dicts don't have a union operation. If they did, and the same key were found in both sets, what would be the value of that key in the union? > 2. Is there a better way to do what I want? The dict.items() view is explicitly set-like and can be unioned, so you can do this: py> dict(d1.items() | d2.items()) As to the question of which value will appear in the union in the case of duplicate keys, it will be whichever one arbitrarily appears later in the iteration order of the intermediate set.
