I need your help slicing a dataframe with a lot of repetitive sequences. For instance:
a = [1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3...]
I tried the drop_duplicates(subset= "", keep="last") options but I got something like a = [1, 2, 3] so only one sequence of numbers is left. For each sequence from 1 to 3, I need to get the last number.
I need the final result to be like: a = [1, 2, 3, 1, 2, 3...]
Thanks in advance
