Write a Python program to pack consecutive duplicates of a given list elements into sublists.

 

Sample Solution:

Python Code:

from itertools import groupby
def pack_consecutive_duplicates(l_nums):
    return [list(group) 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 packing consecutive duplicates of the said list elements into sublists:")
print(pack_consecutive_duplicates(n_list))

Sample Output:

Original list:
[0, 0, 1, 2, 3, 4, 4, 5, 6, 6, 6, 7, 8, 9, 4, 4]

After packing consecutive duplicates of the said list elements into sublists:
[[0, 0], [1], [2], [3], [4, 4], [5], [6, 6, 6], [7], [8], [9], [4, 4]]
