You can use the .update()
method if you don’t need the original d2
any more:
Update the dictionary with the key/value pairs from other, overwriting existing keys. Return
None
.
E.g.:
>>> d1 = {'a': 1, 'b': 2} >>> d2 = {'b': 1, 'c': 3} >>> d2.update(d1) >>> d2 {'a': 1, 'c': 3, 'b': 2}
Update:
Of course you can copy the dictionary first in order to create a new merged one. This might or might not be necessary. In case you have compound objects (objects that contain other objects, like lists or class instances) in your dictionary, copy.deepcopy
should also be considered.
