# Write a Python program to Sort Dictionary by Values Summation # Python3 code to demonstrate working of # Sort Dictionary by Values Summation# Using dictionary comprehension + sum() + sorted()  # initializing dictionarytest_dict = {'Gfg' : [6, 7, 4], 'is' : [4, 3, 2], 'best' : [7, 6, 5]}   # printing original dictionaryprint("The original dictionary is : " + str(test_dict))  # summing all the values using sum()temp1 = {val: sum(int(idx) for idx in key)            for val, key in test_dict.items()}  # using sorted to perform sorting as requiredtemp2 = sorted(temp1.items(), key = lambda ele : temp1[ele[0]])  # rearrange into dictionaryres = {key: val for key, val in temp2}          # printing result print("The sorted dictionary : " + str(res))
