Issue using 3rd party package in a script
I've come across what I thought was a simple problem to solve and perhaps it is, but I need some help solving it.
I want to use a package I downloaded called 'psutil'. Maybe someone has experience using it. Anyway, I installed the package and I can use it without problems in the Python shell but when I tried using it in a script it said no module psutil existed. I then but the psutil folder from the lib\site-packages folder in the same directory as my .py file and now I get a different error:
In the psutil sub-directory there are the following files:
File "C:\Users\Dominic\Documents\programs\psutil\__init__.py", line 77, in <module> import psutil._psmswindows as _psplatform
File "C:\Users\Dominic\Documents\programs\psutil\_psmswindows.py", line 15, in <module> import _psutil_mswindows
ImportError: No module named _psutil_mswindows
Basically I don't know what I'm suppose to do to solve this error. There seems to be at least 1 file missing. How come the module works fine through the shell but not through a script?
My experience installing and using 3rd party packages in python is very limited and any information (even if isn't directly related to this problem) would be useful.

Strange, I have no problems with pyutil installed on Windows7 for either Python27 or Python33.
download Windows installer
Let's hope you didn't save your own script file as pyutil.py

I used exactly the links you quoted. Downloaded the install exe for Python version 3.3. There were no problems in the installation but this is still a problem. I think it is very strange how I can put the command 'import psutil' into the shell and everything works, but when I write a script with it in, suddenly it is a problem?!?!
I think this problem also exists with other 3rd party packages on my system, not just psutil. This would imply that the issue is definitely my system. Using the python shell I used sys.path to check the search path directories, this is what came up:
So everything seems normal there and the lib\site-packages folder is definitely being seen. I read something online about another path variable 'PYTHONPATH'. Don't know much about it though.
['', 'C:\\Python33\\Lib\\idlelib', 'C:\\Windows\\system32\\python33.zip', 'C:\\Python33\\DLLs', 'C:\\Python33\\lib', 'C:\\Python33', 'C:\\Python33\\lib\\site-packages']
