Filter Dictionaries by Values in Kth Key in Python

When it is required to filter dictionaries by values in ‘K’th key in a list, a simple iteration by specifying the condition is used.

Example

Below is a demonstration of the same

my_list = [{"Python": 2, "is": 4, "cool": 11},
   {"Python": 5, "is": 1, "cool": 1},
   {"Python": 7, "is": 3, "cool": 7},
   {"Python": 9, "is": 9, "cool": 8},
   {"Python": 4, "is": 10, "cool": 6}]

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

search_list = [1, 9, 8, 4, 5]

key = "is"

my_result = []

for sub in my_list:
   if sub[key] in search_list:
      my_result.append(sub)

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

Output

The list is :
[{'Python': 2, 'is': 4, 'cool': 11}, {'Python': 5, 'is': 1, 'cool': 1}, {'Python': 7, 'is': 3, 'cool': 7}, {'Python': 9, 'is': 9, 'cool': 8}, {'Python': 4, 'is': 10, 'cool': 6}]
The result is :
[{'Python': 2, 'is': 4, 'cool': 11}, {'Python': 5, 'is': 1, 'cool': 1}, {'Python': 9, 'is': 9, 'cool': 8}]

Explanation

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

• Another list of integers and a key are defined.

• An empty list is defined.

• The list is iterated and if the key is found, the element is appended to the emoty list.

• This is the output.

• It is displayed on the console.
