New submission from Ankit Dhebar:
code snippet
student_tuple = [ ('ykjsdf', 'A', 17, datetime.date(2014,10,15)), ('accjr',
'C', 11, datetime.date(2013,05,05)), ('dgekw', 'B', 5,
datetime.date(1987,03,03)) ]
Output for the above code works as expected.
o/p : [('dgekw', 'B', 5, datetime.date(1987, 3, 3)), ('accjr', 'C', 11,
datetime.date(2013, 5, 5)), ('ykjsdf', 'A', 17, datetime.date(2014, 10, 15))]
but when you make one of the above datetime.date as 'None' like below
student_tuple = [ ('ykjsdf', 'A', 17, datetime.date(2014,10,15)), ('accjr',
'C', 11, None), ('dgekw', 'B', 5, datetime.date(1987,03,03)) ]
o/p : TypeError: can't compare datetime.date to NoneType
In my opinion, the 'NoneType' should appear either in the beginning or towards
the end after sorting is done.
