Merging dictionaries with duplicate keys allows you to combine the key-value pairs from multiple dictionaries into a single dictionary. In this blog post, we will explore different methods to merge dictionaries with duplicate keys in Python.
Method 1: Using the update() method
Python
x
# Method 1: Using the update() methoddict1 = {"name": "John", "age": 30}dict2 = {"city": "New York", "age": 35}merged_dict = dict1.copy()merged_dict.update(dict2)print("Merged Dictionary:", merged_dict)Output:
Merged Dictionary: {‘name’: ‘John’, ‘age’: 35, ‘city’: ‘New York’}
Method 2: Using the double asterisk (**)
Python
# Method 2: Using the double asterisk (**) operatordict1 = {"name": "John", "age": 30}dict2 = {"city": "New York", "age": 35}merged_dict = {**dict1, **dict2}print("Merged Dictionary:", merged_dict)Output:
Merged Dictionary: {‘name’: ‘John’, ‘age’: 35, ‘city’: ‘New York’}
