Python Program - Merge Two Dictionaries

To merge two dictionaries in Python, we can use the update() method or the ** operator.

Here's an example program that demonstrates both methods:

# Merge two dictionaries using the update() method
dict1 = {'a': 1, 'b': 2}
dict2 = {'c': 3, 'd': 4}

merged_dict = dict1.copy()
merged_dict.update(dict2)

print("Merged dictionary using update() method:", merged_dict)

# Merge two dictionaries using the ** operator
dict1 = {'a': 1, 'b': 2}
dict2 = {'c': 3, 'd': 4}

merged_dict = {**dict1, **dict2}

print("Merged dictionary using ** operator:", merged_dict)

In this program, we have two dictionaries dict1 and dict2.

To merge the dictionaries using the update() method, we first make a copy of dict1 and then update it with the items from dict2. The update() method modifies the original dictionary in place.

To merge the dictionaries using the ** operator, we simply use the ** operator with the dictionaries. This creates a new dictionary that contains the items from both dictionaries.

The output of the program is:

Merged dictionary using update() method: {'a': 1, 'b': 2, 'c': 3, 'd': 4}
Merged dictionary using ** operator: {'a': 1, 'b': 2, 'c': 3, 'd': 4}
