Mea culpa -  I had it in my head the OP wanted to treat the files as one 
contiguous one. So yeah:

# something equiv to... (unless it is definitely a fixed range in which
# case (x)range can be used)
data = [ list(open(fname)) for fname in iglob('/home/jon/data*.txt') ]

# then if they ever need to treat it as a contiguous sequence...
all_data = list(chain.from_iterable(data))

Jon.
