Modifying selected column of Python 2D list

I have a 2D list 'sorted_list' and need to modify selected elements of the list. The list consists of a variable number of sub lists, each - with 3 elements.  I need to modify the 3rd element of each sub list.  For example :

[[2, 25, 1], [1, 26, 2], [1, 27, 3], [1, 29, 4]]  .... I need to replace elements 1, 2, 3 and 4 with their corresponding names obtained by looking up a mysql table. The revised list could look something like
[[2, 25, NAME1], [1, 26, NAME2], [1, 27, NAME3], [1, 29, NAME4]]

I have made the attached Function 'convertPizzaNameCOMBO(sorted_list)' which should produce the modified list (attached). It gives however  the attached error message indicating SQL syntax problem (see attached error message)
 

The function seems to be working correctly from a looping standpoint. For example, if I replace sorted_list[][col] with 20 (which is a legitimate ID for looking up the table)  - all the targeted elements in the list will be changed to the name corresponding to 20.   So it appear to be some mysql syntax problem ?

Hopefully you can spot the error - or if my basic approach is incorrect, maybe you can point me in the right direction

Thanks
