Instead of using poll, use select.kqueue() on OSX. It's similar to 'epoll' on Linux in that you can more efficiently register for types of file-descriptor / file system events which can be used in asynchronous code. Much more efficient than polling.
Otherwise, the equivalent is just running a blocking select.select() inside a while True: loop with some sort of timeout?

If you want to use poll in order to not rewrite a bunch of code for kqueue, it is built in to the python compiled from macports (macports.org). You just must specify that python instance explicitly (/opt/local/bin/python2.7 in my case) because OSX's python (/usr/bin/python) will by default be earlier in the search path.

I am unable to import decimal in the terminal for Python 2.7 or 3.3.
Here are the errors I get:

How to I import decimal?

Is there numbers.py in current working directory?
That could be the reason of the problem, because that prevent import of standard library module numbers.

How to import decimal in Python3:
from decimal import Decimal
a = Decimal(25)
print(type(a))
//prints <class 'decimal.Decimal'>

I know I'm late to the game, I ran into this issue too until I realized what I did wrong.
If you have named one your own files "decimal.py", your project will have two modules with the same name "decimal", which would confuse your IDE.
Change the name of your file and try again.

Python on Ubuntu: 'module' object has no attribute 'c_bool'

Using Python 2.7 on Ubuntu 12.10 64Bit gives me the following trouble:

>>> import ctypes

Traceback (most recent call last):

How can I fix this problem?

Do you have a file called "ctypes.py" in the directory where you are working? If so, move it or (preferably) rename it.
