How can I merge two dictionaries in Python?

You can merge two dictionaries using the update() method or the ** unpacking operator. Which method would you like to know more about?

Can you show me an example using the update() method?

Sure! Here's an example:

dict1 = {'a': 1, 'b': 2}
dict2 = {'b': 3, 'c': 4}
dict1.update(dict2)
print(dict1)  # Output: {'a': 1, 'b': 3, 'c': 4}

This merges dict2 into dict1, updating the value of key 'b'.

What about using the ** unpacking operator?

You can use the ** operator like this:

dict1 = {'a': 1, 'b': 2}
dict2 = {'b': 3, 'c': 4}
merged_dict = {**dict1, **dict2}
print(merged_dict)  # Output: {'a': 1, 'b': 3, 'c': 4}

This creates a new dictionary by unpacking both dictionaries.
