Well, you could make a file like this:

    	#rec_fields.py
    	sampleID = 0
    	pos_x = 1
    	#or whatever you do to set up these names

and then in your main file:

    	from rec_fields import *
    	...
    	rec[2033][pos_x]

The only problem is possibly namespace polution, if you want to avoid this 
another method would be:

    	import rec_fields as rf #i think this is the syntax
    	...
    	rec[2033][rf.pos_X]

Which would give you a better grouping. There are at least a few other 
ways, like class attributes, but this should give you a start =)
