I have the following DataFrame. I want to create a column, Participants, accumulative, that for each date accumulates Participants up until that date - i.e.

      Date  Team  Participants  Participants, accumulative
01-01-2023    AA             2                           2
02-01-2023    BB             4                           6
03-01-2023    CC             5                          11
04-01-2023    DD             6                          17
05-01-2023    EE             8                          25

You can look into [pandas cumsum](https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.cumsum.html) – Florent Monin Mar 01 '23 at 08:43
