I can import and run my ?Hello World? module/function in the immediate
window but if I then edit and save the source file I can not see how to
run the modified code without closing and restarting the shell.
If I try and do it all from the IDLE edit window both import module (f5)
and run script (ctrl+f5) open a shell with the cursor in the line below
the prompt and then nothing! Ctrl+f5 in the shell gives me the message
?The buffer for Python Shell is not saved
What am I missing?
