# Python – Extract Similar Key Values

• Last Updated : 11 Oct, 2020

Given a dictionary, extract all values which are from similar keys, i.e contains all similar characters, just jumbled to form each other.

Input : test_dict = {‘gfg’ : 5, ‘ggf’ : 19, ‘gffg’ : 9, ‘gff’ : 3, ‘fgg’ : 3}, tst_wrd = ‘fgg’
Output : [5, 19, 3]
Explanation : gfg, ggf and fgg have values, 5, 19 and 3.

Input : test_dict = {‘gfg’ : 5, ‘gffg’ : 9, ‘gff’ : 3, ‘fgg’ : 3}, tst_wrd = ‘fgg’
Output : [5, 3]
Explanation : gfg and fgg have values, 5 and 3.

Method #1 : Using sorted() + loop

In this, we compare the key after sorting with target key, will have similar elements in correct order, and can be checked for equality. Once with match, their values are extracted.

## Python3

 # Python3 code to demonstrate working of# Extract Similar Key Values# Using loop + sorted()  # initializing dictionarytest_dict = {'gfg': 5, 'ggf': 19, 'gffg': 9, 'gff': 3, 'fgg': 3}  # printing original dictionaryprint("The original dictionary is : " + str(test_dict))  # initializing wordtst_wrd = 'fgg'  res = []for key, val in test_dict.items():      # sorted to get similar key order    if ''.join(list(sorted(key))) == tst_wrd:        res.append(val)  # printing resultprint("The extracted keys : " + str(res))

Output:

The original dictionary is : {‘gfg’: 5, ‘ggf’: 19, ‘gffg’: 9, ‘gff’: 3, ‘fgg’: 3}
The extracted keys : [5, 19, 3]

Method #2 : Using list comprehension + sorted()

In this, we perform similar task as above, just perform using shorthand using sorted() and list comprehension.

## Python3

Output:

The original dictionary is : {‘gfg’: 5, ‘ggf’: 19, ‘gffg’: 9, ‘gff’: 3, ‘fgg’: 3}
The extracted keys : [5, 19, 3]
