Append a Dictionary to a Dictionary

To append a dictionary to another dictionary in Python, you can use the update() method or dictionary unpacking.

Using update():

Output: {'a': 1, 'b': 2, 'c': 3, 'd': 4}

Using Dictionary Unpacking (Python 3.5+):

Output: {'a': 1, 'b': 2, 'c': 3, 'd': 4}

Both approaches add the key-value pairs from dict2 to dict1.
