Wild guess: you do a "from os import *" in p.py. Don't do this, it is evil
<wink>. os.open expects different arguments than the builtin open.
The tutorial and the python docs should contain s.th. like 
"DO NOT USE from module import *!!! IT IS DANGEROUS!!"
(yes I know, multiple ! r a sure sign of a deseased mind)
:)
