#30513 — Editing in IDLE

Hello to the group!

I'm a new Python user and so far I'm enjoying it. One of the many newbie problems I'm having is I can't edit my code in IDLE once it's run or there's an error message. I can only copy the code so far, paste at the bottom and continue coding. Is there something simple I'm missing, or should I be using a different editor?

Thanks in advance!

You are missing how to use IDLE. It has two kinds of windows: 
interactive Shell and Edit windows. The shell more or less emulates the 
interactive interpreter, running one statement at a time. You can put 
the cursor on a previous statement and hit return to make it the current 
statement, where you can edit it. You edit normal multi-statement code 
in edit windows, hit F5 to run, edit, run, edit, run.

I only ever use IDLE in its interactive mode (at which, imho, it's
rather better than the default Python interactive mode, as it
auto-indents). In that mode, you can retrieve previous commands with
Alt-P - at least, that's the keystroke on Windows, not sure if it's
different on other platforms.

For editing code that's to be saved in a .py file, I use SciTE, but a
lot of people do use IDLE for that too. It's a matter of personal
preference.

Thanks for the responses, Terry and Chris, I'll try the shell, alt-P and I'll check out SciTE!
