the problem with writing things via the interactive prompt, is that they "go away" when you log out. you can't look at a listing of your code (or can you?) - you cannot re-edit a function (or can you?). > If you don't have enough experience with Python's interactive prompt, > you might not realise its power yet.When experimenting with Python > code it's much more convenient than the shell.Heavily relying on > interactive work calls all the stronger for an IDE (like IDLE).If you > are really limited to a textual terminal, there are still some nice > environments (e.g. ipython).I'll study the offerings and give a > reccomendation soon.Perhaps I will even adjust the editor/prompt > keybindings to match one another. please check them and see if they fit the bill. i have some personal disliking for IDEs generally - but if the IDE does not hide the program's structure, and does not require too much teaching, i'll consider using it for the course. > BTW, I suggest that code examples in the reference document be written > with outputs from the interactive prompt.E.g. don't just write:: > > "hello " * 3 > > but write:: > > >>> "hello " * 3 > 'hello hello hello ' are you interested in updating the current document and completing it in this format? i'm in favor ;) > (It's also good policy to run all examples to make sure they are > correct.) i write them in a script and run the script. that's how i like to do things - much easier to edit and repeat the tests this way (and you don't always test things in a FIFO order). -- guy "For world domination - press 1, or dial 0, and please hold, for the creator." -- nob o. dy
