I want to filter data that only start timestamp happen before finish timestamp
Here's my data
id finish start
1 2018-02-06 13:24:23 2018-02-06 11:11:23
2 2018-02-06 17:25:01 2018-02-06 08:45:20
3 2018-02-06 05:45:19 2018-02-06 06:18:16
4 2018-02-08 12:23:51 2018-02-06 11:11:59
Here's what I want
id finish start
1 2018-02-06 13:24:23 2018-02-06 11:11:23
2 2018-02-06 17:25:01 2018-02-06 08:45:20
4 2018-02-08 12:23:51 2018-02-06 11:11:59
because df['finish'] is before df['start'] so id 3 is removed
