Python – Shuffle 字典值

给定一个字典，任务是编写一个Python程序来将其值打乱到不同的键。

例子：

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.

方法 #1：使用shuffle() + zip() + dict()

在这里，我们使用shuffle()执行混洗元素的任务，而zip()用于将混洗后的值映射到键。最后使用dict()将结果转换为字典。

# 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))

输出：

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}

方法 #2：使用sample() + zip()

在这里，混洗值的任务是使用随机库的sample()完成的。

# 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))

输出：

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}
