Python – Test if Values Sum is Greater than Keys Sum in dictionary
Given a Dictionary, check if the summation of values is greater than Keys sum.
Input : test_dict = {5:3, 1:3, 10:4, 7:3, 8:1, 9:5}
Output : False
Explanation : Values sum = 19 < 40, which is key sum, i.e false.Input : test_dict = {5:3, 1:4}
Output : True
Explanation : Values sum = 7 > 6, which is key sum, i.e true.
Method #1: Using loop
In this, we compute keys and values sum in separate counter, and after the loop equate the values, if values are greater than Keys summation, True is returned.

# Python3 code to demonstrate working of# Test if Values Sum is Greater than Keys Sum in dictionary# Using loop # initializing dictionarytest_dict = {5: 3, 1: 3, 10: 4, 7: 3, 8: 1, 9: 5} # printing original dictionaryprint("The original dictionary is : " + str(test_dict)) key_sum = 0val_sum = 0 for key in test_dict: # getting sum key_sum += key val_sum += test_dict[key] # checking if val_sum greater than key sumres = val_sum > key_sum # printing resultprint("The required result : " + str(res)) |
Output
The original dictionary is : {5: 3, 1: 3, 10: 4, 7: 3, 8: 1, 9: 5}
The required result : False
Method #2 : Using sum() + values() + keys()
In this way, keys sum and values sum is extracted using keys(), values() and summation using sum(), the required condition is checked and verdict is computed.

Output
The original dictionary is : {5: 3, 1: 3, 10: 4, 7: 3, 8: 1, 9: 5}
The required result : False
