 When IDLE is run, you will probably see the Python Shell window. You can open a new editor window by clicking ‘File → New Window’. Once you have written your program, you should save it (remembering to add .py to the end of your filename). You can then run your Python program by clicking ‘Run → Run Module’ (or by pressing F5). The first python project (called <a href="http://jumpto.cc/ascii">ASCII Art</a>) explains the creating, saving and running of a simple Python program in more detail.
 
-Alternatively, .py files can be created and edited using any text editor e.g. Notepad on Windows, Textedit on MacOS, or Leafpad on Raspbian (Raspberry Pi). These files can also be run from a command line interface or terminal by typing `python` followed by the Python filename e.g. `python hello_world.py`.

These files can also be run from a command line interface or terminal by typing `python3` followed by the Python filename e.g. `python3 hello_world.py`. On Windows you would type `py -3 hello_world.py` instead.
 
 As Python is text-based, children may make typing mistakes (called syntax errors), which may prevent them from running a program. The ‘Notes for Club Leader’ that accompany each Python project gives guidance on common syntax errors, along with information on how they can be avoided.
