[Tutor] handling of tabular data

[Pujo Aji]

Hi Frank,
 you can use Numeric.py it is also powerfull to handle averages, min, max,
matrix algebra, etc..
see: http://www.pfdubois.com/numpy/
 You just need to use a list.
 If your data is big and you need more power I suggest you use database like
mysqldb for python.
It is also fun to combine database and python all together.
 Cheers,
pujo
