This is exactly what it should be doing. The prompt is for interactive
experimentation, not for creating programs. What you need is to use
a text editor (even Notepad under windows would work, provided you
are very careful about using TABs properly (but that's another issue)),
then save the file (e.g. as "myprog.py") and then run it from the
command line using "python myprog.py" where the command "python"
comes from have the directory containing the python.exe file properly
set up in your PATH environment variable.
Or you could just use PythonWin, or IDLE, but I can't provide much
help for you there.
