Write a Python program to remove consecutive duplicates of a given list

from itertools import groupby
def compress(l_nums):
    return [key for key, group in groupby(l_nums)] 
n_list = [0, 0, 1, 2, 3, 4, 4, 5, 6, 6, 6, 7, 8, 9, 4, 4 ]
print("Original list:") 
print(n_list)
print("\nAfter removing consecutive duplicates:")
print(compress(n_list))
