On a Windows PC, using the command line
- Make sure your 'path' environment variable points to your Python executable (perhaps C:\Python25).
See this page for instructions on how to set the path variable in XP.
In Vista, find the control for setting environment variables in 'Start/Control Panel/System and Maintenance/System' and select "Advanced system settings".
- Use notepad to save a copy of the script you're modifying, with a .py extension, in the directory of your choice.
(e.g. "C:\My Documents\Ling472\Assignment 1\elizalike.py")
- Open a command prompt: From the start menu either
select 'All Programs/Accessories/Command Prompt', or
select 'run', and type "cmd" in the window that pops up.
- type "cd" followed by the path to the directory containing your copy of the script.
(e.g. "cd C:\My Documents\Ling472\Assignment 1")
- To run the script, type "python filename.py" in the command window.
- Edit your script, save it, and test it again with "python filename.py".
On a Windows PC, using the Graphical User Interface
Note: this works best for scripts that do not take any arguments.
- Save a copy of the script you're modifying, with a .py extension, in the directory of your choice.
- Associate the .py extension with the Python Interpreter:
In your directory, select 'Folder Options' from the tools menu.
In the File Types tab, click 'New', and enter the extension 'py'
click 'Change' and select the Python Command Line Interpreter
- To run the script, double click it.
On Dante or one of the Treehouse machines
- Log in to Dante using ssh and type S at the initial screen to get a shell.
- Or login to a Treehouse workstation.
- Make a directory for your scripts: mkdir pythonscripts
- Go to that directory: cd pythonscripts
- Make a copy of the starter script you're working on. Save it with a .py extension.
- Use a text editor such as emacs or pico to edit the script.
- To run a script type

- You may find it helpful to have multiple terminal windows open, at least one for editing the script and one for running it.
On a Mac running OS X
- Make a directory, say, inside ~/Documents.
- Save a copy of the python script you're working on in that directory, with the extension .py.
- Edit the python script with emacs or textedit. (NB: With textedit, you'll need to make sure to save the file as plain text rather than rtf.)
- To run the script, in your terminal window, type
- Edit the script with your favorite text editor, and save it.
- Run it again from the terminal window to see the effect of your changes.
