get data of given time range in python when time stamp is not proper-CodePudding

        time          a      b
2021-05-23 22:06:54 10.4    70.1    
2021-05-23 22:21:41 10.7    68.3    
2021-05-23 22:36:28 10.4    69.4    
2021-05-23 22:51:15 9.9     71.7

2021-11-19 08:23:05 21.0    42.0

here time is in the index, not a column. when I did df.between_time("2021-11-17 08:15:00","2021-11-19 08:00:00") it throws the error ValueError: Cannot convert arg ['2021-11-17 08:15:00'] to a time

data frame has not proper time stamp. What i want to do,-: when i pass time range or date range, i want to get all the data between given time.

Thanks

Use truncate:

>>> df.truncate("2021-05-23 23:00:00", "2021-11-19 08:20:00")
                        a     b
time
