Have you considered using your operating system's source of random numbers?
random.SystemRandom and os.urandom return numbers which are
cryptographically sound. They are also based on various sources of
physical randomness (which is sometimes a disadvantage, as the entropy
can run out and then the functions will hang waiting for more entropy to
be collected).

Getting to the point, I get this error when I run my program.
File "/dev/python/absolute/truerandom.py", line 9, in <module>
from urllib import urlopen
ImportError: cannot import name urlopen
Is urllib and/or urlopen deprecated in 3.1.2 or is it something I forgot to do?
Python is running on OSX 10.6, which I upgraded from the default install to
3.1.2.
You should never upgrade the system Python by hand, because parts of the
OS are likely to expect a specific version. You should install it
separately.
But in this case, something is screwy, because that script is written
for Python 2.x and won't run at all under Python 3.x. The fact that you
managed to get as far as an ImportError is weird -- it should fail with
SyntaxError during compilation.
urllib still exists in Python 3.x, but it has been re-organised and
urlopen is now called something else. Instead of
from urllib import urlopen
you need
from urllib.request import urlopen
See the Fine Manual for further details.
