What you should do is, in your terminal, cd into the folder where that file is located and then run the ipython notebook command. This will open a browser window with a list of the ipython files in that folder, which you can then open and edit / run again. </div><div class="gmail_default" style="font-family:tahoma,sans-serif"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">Don't ever use Idle, so can't speak towards what's going on there...</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Sep 29, 2015 at 11:51 AM, Lewit, Douglas <span dir="ltr"><<a href="mailto:d-lewit@neiu.edu" target="_blank">d-lewit@neiu.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><font size="4">Hi William,</font><div><font size="4"><br></font></div><div><font size="4">Thanks for the reply. I think Anaconda is GREAT! However, there are times when I prefer the simplicity of IDLE. What's strange is that IDLE does not have access to Anaconda's modules, even when I use Python's os.chdir( ) command to switch over to the folder/directory that contains those modules! (Or at least I think I did. There are so many files! ) For example, when I'm in Anaconda I can <b><font color="#ff0000">import sympy</font></b> and everything is wonderful. But IDLE returns an error and complains that I'm trying to import a non-existent module. :-( Anaconda is great, but 1) You can't go back and edit previous lines in the Anaconda Terminal, and 2) the <b><font color="#ff0000">ipython notebook</font></b> solves this problem nicely, but I always have problems saving and restarting the notebook's file. On my Mac, the "ipython notebook" command creates a Safari page, and I can use Python from within the Safari page. Great! But then let's say I save the file with a .ipynb extension. If I double-click on this file in the future, Safari opens it up alright, but none of the command lines are executable, and the file isn't much fun to read or look at. I'm probably missing a step or a command or something like that. But yes, in general Anaconda is quite impressive and the installation is pretty easy. In Anaconda all the important modules are at my fingertips, so it is really nice to work with for the most part. But again, IDLE has advantages. In IDLE, I can move the cursor around inside a function's definition to change stuff. Not in the Anaconda Terminal. Once I ENTER over to the next line, I'm stuck! I can't get back. The best I can do is just CNTRL-C and start my function definition over again.</font></div><div><font size="4"><br></font></div><div><font size="4">I think my answer was way too long! Sorry! Just trying to explain what's going on. I just wish there was a way that I could get IDLE to access all the modules that Anaconda can access. Not really sure how to do it without tearing apart my operating system. (And I really don't want to do that! ) I must say that on this particular issue Linux really does have a leg up on Mac OS-X because of Linux's builtin package managers. However, for other things I really prefer Mac OS-X. I wish we could combine the best of both worlds! Let's call it LINAC!!! :-) </font></div><div><font size="4"><br></font></div><div><font size="4">Doug.</font></div><div><font size="4"><br></font></div><div><font size="4"> </font></div></div><div class="gmail_extra"><br><div class="gmail_quote"><span class="">On Tue, Sep 29, 2015 at 8:19 AM, William E.

This Python distribution uses an alternative package manager call conda.
