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

# Python3 code to demonstrate working of
# Test if Values Sum is Greater than Keys Sum in dictionary
# Using loop

# initializing dictionary
test_dict = {5: 3, 1: 3, 10: 4, 7: 3, 8: 1, 9: 5}

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

key_sum = 0
val_sum = 0

for key in test_dict:

    # getting sum
    key_sum += key
    val_sum += test_dict[key]

# checking if val_sum greater than key sum
res = val_sum > key_sum

# printing result
print("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.

Python3

# Python3 code to demonstrate working of
# Test if Values Sum is Greater than Keys Sum in dictionary
# Using sum() + values()  + keys()

# initializing dictionary
test_dict = {5: 3, 1: 3, 10: 4, 7: 3, 8: 1, 9: 5}

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

res = sum(list(test_dict.keys())) < sum(list(test_dict.values()))

# printing result
print("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
