Python – Extract dictionaries with values sum greater than K

When it is required to extract dictionaries with values sum greater than K, a simple iteration and ‘if’ condition is used.

Example

Below is a demonstration of the same −

my_list = [{"Python" : 14, "is" : 18, "fun" : 19},{"Python" : 12, "is": 4, "fun" : 16},
{"Python" : 13, "is": 17, "fun" : 11},{"Python" : 13, "is": 16, "fun" : 13}]

print("The list :")
print(my_list)

K =35
print("The value for K :")
print(K)

my_result = []
for index in my_list:
   sum = 0
   for key in index:
      sum += index[key]
   if sum > K:
      my_result.append(index)

print("The result is :")
print(my_result)

Output

The list :
[{'Python': 14, 'is': 18, 'fun': 19}, {'Python': 12, 'is': 4, 'fun': 16}, {'Python': 13, 'is': 17, 'fun': 11}, {'Python': 13, 'is': 16, 'fun': 13}]
The value for K :
35
The result is :
[{'Python': 14, 'is': 18, 'fun': 19}, {'Python': 13, 'is': 17, 'fun': 11}, {'Python': 13, 'is': 16, 'fun': 13}]

Explanation

• A list of dictionary is defined and displayed on the console.

• The value for K is defined and displayed on the console.

• An empty list is created.

• The list is iterated over, and a sum value is initialized to 0.

• If the specific key is present the list, the element is added to the sum.

• If the sum is greater than ‘K’, the index value is appended to the empty list.

• This list is the output that is displayed on the console.
