[IronPython] importing the os module

Yes thank you. After reading Jims post on IronPython's efficiency issues, I
finally understood what you were talking about. 

Thanx..

Papanii,

The os module i am importing is coming from cpython modules that I have put
in my path. That is the setup that I was talking about.

IronPython 0.9.3 on .NET 2.0.50215.44
Copyright (c) Microsoft Corporation. All rights reserved.
>>> import os
>>> os.__file__
'C:\\IPython\\bin\\Lib\\os.py'

Hmm, I tend to disagree with you on the fact that in standard python os is
not a built in module. Even though nt is built in, the os modules also built
in. But what is confusing is that Anthony posted that he was able to import
the os module like so.

Anthony's post..

Double check your setup, since here is what I get importing os:

IronPython 0.9.3 on .NET 2.0.50215.44

>>> dir(os)

He said it had something to do with my set up. Anyway, in terms of the os
module in standard python I could do something like so.

Import os

doesFileExist = os.path.isdir(FileName)

if(doesFileExist):

      print FileName

else:

     print 'No file'

In terms of using the nt module, how would I implement this?

In standard Python, os is not a built-in module, however, nt module is
built-in. IronPython includes built-in nt moduel (as built-in module
implemented in c#), but not the os. module.

I am not understanding your question about the IO module. There is no "io"
module in neither CPython nor IronPython:

Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import io
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: No module named io

Ok, so I stepped through with the debugger and found out that IO module
wasn't begin called. Are io and os built in modules? Below is a copy of the
stack trace..

You can either use the CPython libraries, or instead of "os" use the "nt"
module which IronPython contains.

Subject: [IronPython] importing the os module

Hi Guys,

          I was testing out Iron Python and I was trying to test out the OS
module but I got the error ..

TraceBack (most recent call last)

            At <shell>

ImportError: No module named os..

Obviously it doesn't exist. Thus is there any means to get around this? 

Thank you
