Simple example of parsing a binary file (reads 1024 bytes, aka 1MB at a time).
#!/usr/bin/python
import os, sys
fpath = sys.argv[1]
size = os.stat(fpath)[6]
print size, (size / 1024.0)
file = open(fpath, "rb")
count = 0
while 1:
chunk = file.read(1024)
if not chunk:
break
count += 1
print ".",
print
file.close()
print count, "megabytes"
