I don't know what you did with your Python installation, but for me this works perfectly.
test3.py contains: <code> import sys print sys.stdin.readlines() </code> test.txt contains: <code> Testline1 Testline2 </code> Output of 'python test3.py < test.txt' is: <code> ['Testline1\n', 'Testline2'] </code> Just plain simple and just works.
