Programming Example

A dictionary D1 has values in the form of lists of numbers. Write a program to create a new dictionary D2 having same keys as D1 but values as the sum of the list elements.




D1 = {'A': [1, 2, 3], 'B': [4, 5, 6]}


D2 is {'A':6, 'B': 15}


dic1 = eval(input("Enter dictionary : "))
dic2 = {}
for i in dic1 :
      lst = dic1[ i ]
      sum_of_num = sum( lst )
      dic2 [ i ] = sum_of_num

Enter dictionary :  {"list 1":[1,2,3,4],"list 2":[4,5,6,7],"list 3":[4,2,3]}

{'list 1': 10, 'list 2': 22, 'list 3': 9}
