Given a dictionary in Python, the task is to write a Python program to change the value in one of the key-value pairs. This article discusses mechanisms to do this effectively.

Examples:

Input: {'hari': 1, 'dita': 2}
Output: {'hari': 1, 'dita': 4}

Input: {'hari': 1, 'dita': 2}
Output: {'hari': 3, 'dita': 5}

Changing Values of a Dictionary

Method 1

In this we refer to the key of the value to be changed and supply it with a new value.

Example:

Output:

initial dictionary- {‘hari’: 1, ‘dita’: 2}
 

dictionary after modification- {‘hari’: 1, ‘dita’: 4}

Method 2: 

In this method we use zip() function, which aggregates the iterable and combines them into a tuple form.

Example:

Output:

initial dictionary- {‘hari’: 1, ‘dita’: 2} 

dictionary after modification- {‘hari’: 3, ‘dita’: 5}
