EasyDictionary Programs · 4 of 94

Write a Python program to concatenate two dictionaries.

Input

{"Name": "Harry", "Rollno": 345, "Address": "Jordan"}, {"Age": 25, "salary": "$25k"}

Output

{'Name': 'Harry', 'Rollno': 345, 'Address': 'Jordan', 'Age': 25, 'salary': '$25k'}
{'Name': 'Harry', 'Rollno': 345, 'Address': 'Jordan', 'Age': 25, 'salary': '$25k'}

Approach

| (Python 3.9+) creates a merged dict; update changes one in place.

Solution

Python

dict1 = {"Name": "Harry", "Rollno": 345, "Address": "Jordan"}dict2 = {"Age": 25, "salary": "$25k"}print(dict1 | dict2)dict1.update(dict2)print(dict1)

Output

{'Name': 'Harry', 'Rollno': 345, 'Address': 'Jordan', 'Age': 25, 'salary': '$25k'}
{'Name': 'Harry', 'Rollno': 345, 'Address': 'Jordan', 'Age': 25, 'salary': '$25k'}
