Is every row in your Nested List its own list object with length greater than 0 ?
The majority of your rows are likely list objects with multiple items, giving it a :
len ( row ) > 1
But I'm guessing there may be at least one Row in your Nested List that has a length of 0. In other words whereas most of your rows look like this :
[ 'First Item' , 2 , "3rd Item" ]
There may be one Row that looks like this :
[ ]
And you cannot sort with operator.itemgetter unless every row in that nested list has an item at index number 0 ( or another column number you choose to input in your itemgetter ).
