Your original post said:

making it hard to know what sort of data is in this file.
So I guess it would help to have some sample data to work with, even
if it's just some dummy data and a raw processing loop without doing
anything inside it. Something like the output of either of these
$ xxd forward_data.txt | head -50 > forward_head.txt
$ od forward_data.txt | head -50 > forward_head.txt
plus a basic loop to show how you're extracting the values:
for line in file("forward_head.txt"):
data1, data2, data3 = process(line)
and how you want to reverse over them:
for line in file("reversed.txt"):
if same_processing_as_forward_source:
data1, data2, data3 = process(line)
else:
data1, data2, data3 = other_process(line)
or do you want something more like
for line in super_reverse_magic(file("forward_head.txt")):
data1, data2, data3 = process(line)
?
