please click see image

you can use aggregate,

consider df

    date    id 0   2016-3-28 00:56:43  1 1   2017-3-28 00:56:43  1 2   2005-3-28 00:56:43  1 3   2010-3-28 00:56:43  1 4   2002-3-28 00:56:43  1 5   2017-3-29 00:56:43  1 6   2004-3-28 00:56:43  5 7   2002-3-21 00:56:43  5 8   2015-3-28 00:56:43  5 9   2017-4-28 00:56:43  5 10  2009-3-28 00:56:43  5 11  2007-3-28 00:56:43  5

you can min , max date each id using

df.groupby('id').date.agg(['min', 'max']).reset_index()

you get

    id  min                 max 0   1   2002-3-28 00:56:43  2017-3-29 00:56:43 1   5   2002-3-21 00:56:43  2017-4-28 00:56:43
