Python | Extract filtered Dictionary Values
  • Last Updated : 23 Jan, 2020

While working with Python dictionaries, there can be cases in which we are just concerned about getting the filtered values list and don’t care about keys. This is yet another essential utility and solution to it should be known and discussed. Let’s perform this task through certain methods.

Method #1 : Using loop + keys()
The first method that comes to mind to achieve this task is the use of loop to access each filtered key’s value and append it into a list and return it. This can be one of method to perform this task.




# Python3 code to demonstrate working of
# Extract filtered Dictionary Values
# Using loop + keys()
  
# initializing dictionary
test_dict = {'gfg' : 1, 'is' : 2, 'best' : 3}
  
# printing original dictionary
print("The original dictionary is : " + str(test_dict))
  
# initializing K 
K = 2
  
# Extract filtered Dictionary Values
# Using loop + keys()
res = []
for key in test_dict.keys() :
    if test_dict[key] >= K:
        res.append(test_dict[key])
  
# printing result
print("The list of filtered values is : " + str(res))
Output :
The original dictionary is : {'best': 3, 'gfg': 1, 'is': 2}
The list of filtered values is : [3, 2]

 

Method #2 : Using values()
This task can also be performed using the inbuilt function of values(). This is the best and most Pythonic way to perform this particular task and returns the filtered exact desired result.






# Python3 code to demonstrate working of
# Extract filtered Dictionary Values
# Using values()
  
# initializing dictionary
test_dict = {'gfg' : 1, 'is' : 2, 'best' : 3}
  
# printing original dictionary
print("The original dictionary is : " + str(test_dict))
  
# initializing K 
K = 2
  
# Extract filtered Dictionary Values
# Using values()
temp = list(test_dict.values())
res = [ele for ele in temp if ele >= K]
  
# printing result
print("The list of filtered values is : " + str(res))
Output :
The original dictionary is : {'best': 3, 'gfg': 1, 'is': 2}
The list of filtered values is : [3, 2]
