Drop Dublicates, if they are in a row in Python

I got list like:

[1,1,5,4,6,6,5]

and I want to drop the element of list, if its get repeated.

Output:
[1,5,4,6,5]

I can only find solution for "normal" Duplicate-Problems.

>Solution :

You can use itertools.groupby and just pull the key for each group.

from itertools import groupby

[k for k, _ in groupby([1,1,5,4,6,6,5])]
# returns:
[1, 5, 4, 6, 5]
