Hi!

The code below is an example, adapt it as you need.

input_dict = {1: [2, 3], 2: [10], 3: [4], 4: [], 5: [6, 7], 6: [], 7: [8], 8: [9], 9: [10], 10: []}

def get_values(number):
    result = {}
    current_values = input_dict[number]
    if current_values.__len__() >= 1:
        for current_value in current_values:
            if input_dict[current_value].__len__() >= 1:
                result[current_value] = dict.fromkeys(input_dict[current_value],
                                                      get_values(input_dict[current_value][0]) or {})

    return result

values = {}
for i in range(1, input_dict.__len__()):
    if input_dict[i].__len__() > 1:
        values[i] = get_values(i)

Best regards!
