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 follows; 109 345 2 1234556 To read this file I created the following test script (trying to copy something I saw on Guido's blog - http://neopythonic.blogspot.com/2008/10/sorting-million-32-bit-integers-in-2mb.html ): import array assert array.array('i').itemsize == 4 bufferSize = 2 f=open("sillyNums.txt","r") data = array.array('i') data.fromstring(f.read(data.itemsize* bufferSize)) print data The output was nonsense: array('i', [171520049, 171258931]) I assume this has something to do with my incorrectly specifying how the various bit/bytes line up. Does anyone know if there's a simple explanation of how I can do this correctly, or why I can't do it at all? Thanks, Steven
