Python – Extract dictionaries with values sum greater than K

Python Server Side Programming Programming

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.
