使用随机值构建字典的Python程序

给定 List，我们的任务是编写一个Python程序来构造字典，其中的值是从范围中随机选择的。

例子：

Input : test_list = ["Gfg", "is", "Best"], i, j = 2, 9
Output : {'Gfg': 3, 'is': 9, 'Best': 4}
Explanation : Random values assigned between 2 and 9.

Input : test_list = ["Gfg", "is", "Best"], i, j = 2, 10
Output : {'Gfg': 3, 'is': 9, 'Best': 10}
Explanation : Random values assigned between 2 and 10.

方法 #1：使用randint() +循环

在此，我们遍历列表中的每个元素并分配使用 randint() 选择的随机数来构造键值对字典。

Python3

# Python3 code to demonstrate working of
# Construct dictionary using random values
# Using randint() + loop
from random import randint
 
# initializing list
test_list = ["Gfg", "is", "Best"]
 
# printing original list
print("The original list is : " + str(test_list))
 
# initializing range
i, j = 2, 9
 
res = dict()
for ele in test_list:
     
    # assigning random elements
    res[ele] = randint(i, j)
 
# printing result
print("Random range initialized dictionary : " + str(res))

输出：

The original list is : [‘Gfg’, ‘is’, ‘Best’]

Random range initialized dictionary : {‘Gfg’: 5, ‘is’: 7, ‘Best’: 8}

方法 #2：使用字典理解+ randint()

在这种情况下，我们以与上述方法类似的方式执行任务，唯一的区别是使用字典理解以速记方式分配字典。

# Using randint() + loop
from random import randint
 
# initializing list
test_list = ["Gfg", "is", "Best"]
 
# printing original list
print("The original list is : " + str(test_list))
 
# initializing range
i, j = 2, 9
 
# assigning random elements
# dictionary comprehension used as shorthand
res = {ele : randint(i, j) for ele in test_list}
 
# printing result
print("Random range initialized dictionary : " + str(res))

输出：

The original list is : [‘Gfg’, ‘is’, ‘Best’]

Random range initialized dictionary : {‘Gfg’: 4, ‘is’: 2, ‘Best’: 6}
