One way is to use python dicts. Pseudocode:

arrays = {}
integer = 0
for file in allfiles:
	integer +=1
	data = file.read()
	arrays['a' + '%d' % integer] = data

I would consider using the filename as the key instead of a1, a2, etc. That way you have that information readily available as well.

Good luck,
Paul.
