I would like to automate running virtualenv with a python script by:

Thats almost certainly the wrong approach.
Instead of trying to automate what the user does in the terminal replace
the terminal with Python.
Run the cd command from within Python (os.chdir())
Run Activate from within Python (this is where os.system()
could be used, but subprocess.call() is considered better
practice.
I found some examples of using os.system() to get gnome-terminal to open
but I can't figure out how then cd to the proper directory in the new
terminal.
You can't. os.system() just runs a command it has no way to interaxct5
with the command, you do that manually. Its perfectly fine for
displaying a directory listing (although os.listdir() would be better)
or sending a file to a printer, or even opening a terminal/editor
for the user to interact with. But its no good for your program
interacting with it. Thats what subprocess is for.
Alan and the others that offered advice, thanks. I see that I have taken
the wrong approach. My intent was to automate something I was doing
manually time after time and learn a little more Python as well.
My biggest frustration right now is that I can't find any documentation
on how to use os.system(). Looking at the docs on the Python site I
don't see system() under the os module.
You should, although they don;t have a lot to say...

Googling hasn't helped.
When you know the module use the browser search tools on the page itself
- that's how I found it. I searched for os.system and it
was the 3rd occurence.
My mistake. I went to the Docs page and clicked on modules and then os.
For some reason as I was scrolling down the page I thought the subject
had changed and stopped reading. Now I see I stopped reading to soon as
it is much further down the page.
Thanks, Jim
