I have the following dataframe.
df = pd.DataFrame(
{'name' : ['Khan','Khan','Khan','Dean','Dean','Dean'],
'start_date' : ['01-01-2020','04-02-2020','02-03-2020','09-04-2020','06-08-2020','12-12-2020'],
'end_date' : ['03-01-2020', '09-02-2020','02-03-2020','15-05-2020','19-08-2020','31-12-2020'],
'holiday_type' : ['holiday','holiday','sick leave','holiday','holiday','sick leave']
} )
df[['start_date','end_date']] = df[['start_date','end_date']].apply(pd.to_datetime,format='%d-%m-%Y')
print(df)
name start_date end_date holiday_type
0 Khan 2020-01-01 2020-01-03 holiday
1 Khan 2020-02-04 2020-02-09 holiday
2 Khan 2020-03-02 2020-03-02 sick leave
3 Dean 2020-04-09 2020-05-15 holiday
4 Dean 2020-08-06 2020-08-19 holiday
5 Dean 2020-12-12 2020-12-31 sick leave
I'm attempting to re-sample the data by start and end date without over lapping i.e i don't want a table for Khan that starts on the 2020-01-02 and ends on 2020-03-02
my own attempt as been to melt, index and use groupby.resample however I'm unsure how to only group by each start and end date, a cumulative count ? but it doesn't seem very efficent either.
ideal output :
name date_range holiday_type
0 Khan 2020-01-01 holiday
1 Khan 2020-02-01 holiday
2 Khan 2020-03-01 holiday # < end of holiday 1
3 Khan 2020-04-02 holiday
4 Khan 2020-05-02 holiday
5 Khan 2020-06-02 holiday
6 Khan 2020-07-02 holiday
7 Khan 2020-08-02 holiday
8 Khan 2020-09-02 holiday # end of holiday 2
9 Khan 2020-02-03 sick leave # one day sick leave, can also have one day holiday.
