Why am I getting an import error for importing process on python 3.3?

I am receiving the following error when importing Process in python 3.3. Is there any reason I would get such an error, or is this a bug? I am running the django server in another terminal window, but I doubt that would have anything to do with this.

Python 3.3.2 (default, Nov  8 2013, 13:38:57) 
[GCC 4.8.2 20131017 (Red Hat 4.8.2-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.
# extension module loaded from '/usr/lib64/python3.3/lib-dynload/readline.cpython-33m.so'
import 'readline' # <_frozen_importlib.ExtensionFileLoader object at 0x7f8a00fc1050>
>>> from multiprocessing import Process
# ./__pycache__/multiprocessing.cpython-33.pyc matches ./multiprocessing.py

The line File "./multiprocessing.py" in your traceback suggests that you have a file named multiprocessing.py in the working directory.

Try removing/renaming it, because it shadows the real multiprocessing module. The problem here is that the very first entry in your sys.path is always '', so a file in the working dir will be preferred to a standard module when doing an import.
