If you want to make a bunch of constants available:

-- file constants.py ---

sampleID, pos_x, pos_y, etc = range(4)

-- every where else ---
from constants import *

---

You might want to consider writing your own classes for the data instead of
reusing lists.  Then you would write 'rec[2033].pos_y'.
