Python program to divide dictionary and its keys into K equal dictionaries
• Last Updated : 25 Oct, 2020

Given a dictionary, divide it into an equal dictionary list of size k, by dividing each key’s value.

Input : test_dict = {“Gfg” : 9, “is” : 6, “best” : 12} , K = 3
Output : [{‘Gfg’: 3.0, ‘is’: 2.0, ‘best’: 4.0}, {‘Gfg’: 3.0, ‘is’: 2.0, ‘best’: 4.0}, {‘Gfg’: 3.0, ‘is’: 2.0, ‘best’: 4.0}]
Explanation : Values distributed equally among dictionaries.

Input : test_dict = {“Gfg” : 6, “is” : 4, “best” : 2} , K = 2
Output : [{‘Gfg’: 3.0, ‘is’: 2.0, ‘best’: 1.0}, {‘Gfg’: 3.0, ‘is’: 2.0, ‘best’: 1.0}]
Explanation : Values distributed equally among dictionaries.

Method #1: Using loop

This is one of the ways in which this task can be performed. In this, we compute each required key’s value and append each dictionary into the dictionaries list.

## Python3

 `# Python3 code to demonstrate working of``# Divide dictionary into K equal dictionaries``# Using loop`` ` `# initializing dictionary``test_dict ``=` `{``"Gfg"``: ``20``, ``"is"``: ``36``, ``"best"``: ``100``}`` ` `# printing original dictionary``print``(``"The original dictionary is : "` `+` `str``(test_dict))`` ` `# initializing size``K ``=` `4`` ` `# contructing new dict``temp ``=` `dict``()``for` `key ``in` `test_dict:``    ``temp[key] ``=` `test_dict[key] ``/` `4`` ` `# creating list``res ``=` `[]``for` `idx ``in` `range``(K):``    ``res.append(temp)`` ` `# printing result``print``(``"Required dictionary list : "` `+` `str``(res))`

Output:

The original dictionary is : {‘Gfg’: 20, ‘is’: 36, ‘best’: 100}
Required dictionary list : [{‘Gfg’: 5.0, ‘is’: 9.0, ‘best’: 25.0}, {‘Gfg’: 5.0, ‘is’: 9.0, ‘best’: 25.0}, {‘Gfg’: 5.0, ‘is’: 9.0, ‘best’: 25.0}, {‘Gfg’: 5.0, ‘is’: 9.0, ‘best’: 25.0}]

Method #2 : Using dictionary comprehension + list comprehension

This is yet another way in which this task can be performed. In this, we form dictionary using dictionary comprehension and list using list comprehension as  a shorthand to solve this problem.

## Python3

 `# Python3 code to demonstrate working of``# Divide dictionary into K equal dictionaries``# Using dictionary comprehension + list comprehension`` ` ` ` `# function to divide dictionary``# and keys into K equal dictionaries``def` `divideDictKeys(dictionary, K):`` ` `    ``# contructing new dict``    ``# using dictionary comprehension``    ``temp ``=` `{key: test_dict[key] ``/` `K ``for` `key ``in` `test_dict}`` ` `    ``# creating list``    ``# using list comprehension``    ``res ``=` `[temp ``for` `idx ``in` `range``(K)]`` ` `    ``return` `str``(res)`` ` ` ` `# driver code`` ` `# initializing dictionary``test_dict ``=` `{``"Gfg"``: ``20``, ``"is"``: ``36``, ``"best"``: ``100``}`` ` `# initializing size``K ``=` `4`` ` `# printing original dictionary``print``(``"The original dictionary is : "` `+` `str``(test_dict))`` ` `# printing result``print``(``"Required dictionary list : "` `+` `divideDictKeys(test_dict, K))`

Output:

The original dictionary is : {‘Gfg’: 20, ‘is’: 36, ‘best’: 100}
Required dictionary list : [{‘Gfg’: 5.0, ‘is’: 9.0, ‘best’: 25.0}, {‘Gfg’: 5.0, ‘is’: 9.0, ‘best’: 25.0}, {‘Gfg’: 5.0, ‘is’: 9.0, ‘best’: 25.0}, {‘Gfg’: 5.0, ‘is’: 9.0, ‘best’: 25.0}]
