Python: Convert more than one list to nested dictionary

Python dictionary: Exercise-43 with Solution

Write a Python program to convert more than one list to nested dictionary.

Sample Solution:

Python Code:

def nested_dictionary(l1, l2, l3):
     result = [{x: {y: z}} for (x, y, z) in zip(l1, l2, l3)]
     return result

student_id = ["S001", "S002", "S003", "S004"] 
student_name = ["Adina Park", "Leyton Marsh", "Duncan Boyle", "Saim Richards"] 
student_grade = [85, 98, 89, 92]
print("Original strings:")
print(student_id)
print(student_name)
print(student_grade)
print("\nNested dictionary:")
ch='a'
print(nested_dictionary(student_id, student_name, student_grade))

Sample Output:

Original strings:
['S001', 'S002', 'S003', 'S004']
['Adina Park', 'Leyton Marsh', 'Duncan Boyle', 'Saim Richards']
[85, 98, 89, 92]

Nested dictionary:
[{'S001': {'Adina Park': 85}}, {'S002': {'Leyton Marsh': 98}}, {'S003': {'Duncan Boyle': 89}}, {'S004': {'Saim Richards': 92}}]
