Python – Shuffle dictionary Values

Given a dictionary, the task is to write a python program to shuffle its values to different keys.

Examples:

Input: test_dict = {“gfg” : 1, “is” : 7, “best” : 8, “for” : 3, “geeks” : 9}

Output : {“gfg” : 9, “is” : 8, “best” : 7, “for” : 3, “geeks” : 1}

Explanation : Keys are at same position but values are shuffled.

Input : test_dict = {“gfg” : 7, “is” : 1, “best” : 8, “for” : 3, “geeks” : 9}

Output : {“gfg” : 9, “is” : 8, “best” : 7, “for” : 3, “geeks” : 1}

Explanation : Keys are at same position but values are shuffled.

Method #1 : Using shuffle() + zip() + dict()

In this, we perform the task of shuffling elements using shuffle(), and zip() is used to map the shuffled values to keys. In the end, dict() is used to convert the result to a dictionary.

Python3

# Python3 code to demonstrate working of
# Shuffle dictionary Values
# Using shuffle() + zip() + dict()
import random

# initializing dictionary
test_dict = {"gfg": 1, "is": 7, "best": 8,
             "for": 3, "geeks": 9}

# printing original dictionary
print("The original dictionary is : " + str(test_dict))

# shuffling values
temp = list(test_dict.values())
random.shuffle(temp)

# reassigning to keys
res = dict(zip(test_dict, temp))

# printing result
print("The shuffled dictionary : " + str(res))

Output:

The original dictionary is : {‘gfg’: 1, ‘is’: 7, ‘best’: 8, ‘for’: 3, ‘geeks’: 9}

The shuffled dictionary : {‘gfg’: 1, ‘is’: 7, ‘best’: 3, ‘for’: 9, ‘geeks’: 8}

Method #2 : Using sample() + zip()

In this, the task of shuffling values is done using sample() of random library.

Python3

# Python3 code to demonstrate working of
# Shuffle dictionary Values
# Using sample() + zip()
from random import sample

# initializing dictionary
test_dict = {"gfg": 1, "is": 7, "best": 8,
             "for": 3, "geeks": 9}

# printing original dictionary
print("The original dictionary is : " + str(test_dict))

# reassigning to keys
res = dict(zip(test_dict, sample(list(test_dict.values()),
                                 len(test_dict))))

# printing result
print("The shuffled dictionary : " + str(res))

Output:

The original dictionary is : {‘gfg’: 1, ‘is’: 7, ‘best’: 8, ‘for’: 3, ‘geeks’: 9}

The shuffled dictionary : {‘gfg’: 8, ‘is’: 9, ‘best’: 1, ‘for’: 3, ‘geeks’: 7}
