Write a Python program to count number of unique sublists within a given list

def unique_sublists(input_list):
    result ={}
    for l in input_list: 
        result.setdefault(tuple(l), list()).append(1) 
    for a, b in result.items(): 
        result[a] = sum(b)
    return result

list1 = [[1, 3], [5, 7], [1, 3], [13, 15, 17], [5, 7], [9, 11]] 
print("Original list:")
print(list1)  
print("Number of unique lists of the said list:")
print(unique_sublists(list1)) 

color1 = [["green", "orange"], ["black"], ["green", "orange"], ["white"]]
print("\nOriginal list:")
print(color1)  
print("Number of unique lists of the said list:")
print(unique_sublists(color1))
