Thanks for a quick response. Perhaps I was being unclear - in py3k, 
given the following code and assuming no errors arise:

 > f = open("foo", "w+b")
 > f.write(b'test')
 > f.seek(0)
 > print(f.read(4))

What is the printed result supposed to be?

i) b'test'
ii) never b'test'
iii) platform dependent/undefined/other

All the best,
