You can use any text editor to write a python script. A simple editor which might be present ont the Pi is called "nano". It shows the hotkeys to store the text and quit the editor, and thus should be self-explanatory: $ nano helloworld.py Once you have written your simple script you can look at it with the "cat" command: $ cat helloworld.py #!/usr/bin/env python print "Hello world" Invoke it with: $ python helloworld.py Hello world You can also make your script "executable" which means that the first line controls which program is used to run it: $ chmod +x helloworld.py $ ./helloworld.py Hello world $ If the script is in a directory listed in the PATH environment variable you can omit the path (the "./" in the above example): $ mv helloworld.py ~/bin $ helloworld.py Hello world PS: I ran the above demo on a Linux system, but not on the Raspberry Pi, so if something doesn't work as shown above it's probably due to the difference between the two systems. -- https://mail.python.org/mailman/listinfo/python-list
