Python Program to Concatenate Two Dictionaries Into One

When it is required to concatenate two dictionaries into a single entity, the ‘update’ method can be used.

A dictionary is a ‘key-value’ pair.

Below is a demonstration for the same −

Example

 Live Demo

my_dict_1 = {'J':12,'W':22} my_dict_2 = {'M':67} print("The first dictionary is :") print(my_dict_1) print("The second dictionary is :") print(my_dict_2) my_dict_1.update(my_dict_2) print("The concatenated dictionary is :") print(my_dict_1)

Output

The first dictionary is : {'J': 12, 'W': 22} The second dictionary is : {'M': 67} The concatenated dictionary is : {'J': 12, 'W': 22, 'M': 67}

Explanation

Two dictionaries are defined, and are displayed on the console. 

• The ‘update’ method is called on the first dictionary by passing second dictionary as parameter. 
• This would help concatenate the dictionary. 
• This is displayed on the console.
