How to Create Nested Dictionary in Python with 3 lists

Question

Let us Suppose, I have created 3 lists and I want to create a dictionary for it. e.g.

a= [\'A\', \'B\', \'C\', \'D\']
b =[1, 2, 3, 4]
c = [9, 8, 7, 6]
         


        

Answer 1

You can also use map() here:

a = ['A', 'B', 'C', 'D']
b = [1, 2, 3, 4]
c = [9, 8, 7, 6]

dct = dict(map(lambda x, y, z : (x, {str(y): str(z)}), a, b, c))

print(dct)

Which outputs:

{'A': {'1': '9'}, 'B': {'2': '8'}, 'C': {'3': '7'}, 'D': {'4': '6'}}
