QUESTIONS

What will be the output of the following code snippet?
x = {"a": 1, "b": 2}
y = {"b": 3, "c": 4}
z = {**x, **y}
print(z)

Right Answer:

The ** operator is used for dictionary unpacking, combining the key-value pairs of two dictionaries. If there are duplicate keys, the value from the second dictionary overrides the value from the first dictionary. Therefore, the output will be {“a”: 1, “b”: 3, “c”: 4}.
