[Tutor] array of different datatypes

[Dinesh B Vadhia]

Thanks Steve.  How do you sort on the second element of each list to get:

a' = [[42, 'fish'],
        [1, 'hello']
        [2, 'world']
        ]

If by "array" you mean a regular Python list, the data type of
every single element may be different.  So it's just how lists
always work.

a = [[1, 'hello'],
      [2, 'world'],
      [42, 'fish'],
     ]
