I Need a Couple of Tips for Windows to Get Started on IPython

Community matplotlib-users
1

I've seen the tutorial, but need something more. How do I know what folder I'm in? How do I move from where I am to, for example, C:\abc\def? So far I've tried various combinations like this:

cd ..
cd C:\
pwd (yes, I know it's not windows)

I tried %cd .., and that may have moved me but I seem to get back to the same place.

I seem to be in C:\Documents and Settings\administrator. If I doa %cp ..\\ it looks like I get to C:\, but follwing that with pwd gets me back to where I started--C:\Documents and Settings\administrator.

If I want to execute a program with %run, I need to be where abc.py is or, perhaps say something like %run C:\myPyPrograms\abc.py.
Dir doesn't work and I haven't been able to even see what's in the folder.

Wayne,

Are you using the IPython shell? If so, cd, pwd, ls, etc will work just fine.

If you using the standard python shell, AFAIK, you need to import the os module and use that to navigate.

Ipython session:

Hi, I'm using IPython raw. I guess I'm not sure what a shell is in this
case. I used to work with Linux years ago and the shell concept was
clear there. I'm now simply a Win XP user. What advantages would be
available to use a shell?

In part of the thread above,(posted 57 minutes after the hour, I asked
how copy and paste operate? Quick IPyton seems to think it works quite
like a Win copy and paste. It doesn't work for me.

Below you've manage to post a session. How did that happen? Is there a
file that I can pick up that contains the log? From the ref manual, I
see this:

···

===============

      Manual capture of command output�
<http://ipython.scipy.org/doc/manual/html/interactive/reference.html#manual-capture-of-command-output&gt;

If the input line begins with two exclamation marks, !!, the command is
executed but its output is captured and returned as a python list, split
on newlines. Any output sent by the subprocess to standard error is
printed separately, so that the resulting list only captures standard
output. The !! syntax is a shorthand for the %sx magic command.

Finally, the %sc magic (short for �shell capture�) is similar to %sx,
but allowing more fine-grained control of the capture details, and ...
===============end

Maybe this is somehow you did it?
