Working with date indexes (pandas) - dervast - Apr-05-2019 Hi all, I have a dataset with time stamps and I am happy that I can use timestamps as indexes. I have an issue though that I do not know how, I can make variables of time periods that the indexing will understand. For example in the data below data_test.index[0] [22]: Timestamp('2019-02-08 14:10:07.409000') how I can pick with variables (with fixes string is easy) rows that are inside that time period? Also how I can make a new time variable that now includes a shift? For example something like data_test.index[0].timedelta(milliseconds=500) does not work but the idea is to be able to to have a rolling window based on time stamps that returns me subsets of the initial data frame (pandas). Can you please suggest me which functions to use? Thanks a lot Alex |
