I've been trying to use the Array class to read 32-bit integers from a
file. There is one integer per line and the integers are stored as text.
For problem specific reasons, I only am allowed to read 2 lines (2 32-bit
integers) at a time.
To test this, I made a small sample file (sillyNums.txt) as

Assuming this is a real task and not a homework problem, then
I'd do it this way:
$ cd [directory containing 50 test files]
$ (for file in *; do head -n11 $file | tail -n5; done)
>/path/to/results-file.txt
I'd use sed:
sed -ns 7,11p /source/path/*.txt >/path/to/results.txt

Files can be iterated line-by-line, so this idiom:

you can use pydoc's pager from your program:
import pydoc
text = open(filename).read()
pydoc.pager(text)
