Given a dictonary, extract ith element of K key’s value list.
Input : test_dict = {‘Gfg’ : [6, 7, 3, 1], ‘is’ : [9, 1, 4], ‘best’ : [10, 7, 4]}, K = ‘Gfg’, i = 1
Output : 7
Explanation : 1st index of ‘Gfg”s value is 7.Input : test_dict = {‘Gfg’ : [6, 7, 3, 1], ‘is’ : [9, 1, 4], ‘best’ : [10, 7, 4]}, K = ‘best’, i = 0
Output : 10
Explanation : 0th index of ‘best”s value is 10.
Method : Using + get()
This is one of the ways in which this task can be performed. In this, we extract the key’s value using get() and then value is extracted after checking for K being less than list length.
Python3
# Python3 code to demonstrate working of # Extract ith element of K key's value # Using get() # initializing dictionary test_dict = {'Gfg' : [6, 7, 3, 1], 'is' : [9, 1, 4], 'best' : [10, 7, 4]} # printing original dictionary print("The original dictionary is : " + str(test_dict)) # initializing K K = 'Gfg' # initializing i i = 2 # using get() to get the required value temp = test_dict.get(K) res = None# checking for non empty dict and length constraints if temp and len(temp) >= i: res = temp[i] # printing result print("The extracted value : " + str(res)) |
The original dictionary is : {'Gfg': [6, 7, 3, 1], 'is': [9, 1, 4], 'best': [10, 7, 4]}
The extracted value : 3
