I was spurred to ask this question by a painful development experience full of Up Up Up Up Up Enter Up Up Up Up Up Enter ... keypresses to repeat a previous set of Python commands/statements that weren't worth putting in a script file, or which I wanted to make very minor changes to on each iteration.
Using Windows for a couple of decades, I am not spoiled by bash ;-).
Idle lets me directly click on a previous statement and hit enter to make it the current statement. Edit if desired and hit enter again to execute again in the current workspace. But I agree with Oscar that even a few lines are worth a temporary script file.
As soon as I find myself doing this I quit the interpreter and start ipython. The feature that ipython has that makes what you are doing much easier is the magic %edit command. Just type
In : edit tmp.py
and your favourite editor will open up allowing you to write/edit some code. When you close the editor, ipython will run the code from tmp.py within the interactive session (as if you had typed it in directly). If you want to rerun that code with modifications just type 'edit tmp.py' again and you can make the modifications within your editor.
In Idle, I click File - Recent files - .../tem.py (in my misc. files directory) to open an edit window, which I leave open all day. Running from the edit window does restart the workspace, so one would have to cut and paste to not restart. I seldom want to re-run multiple lines without restarting.
If I want to keep the 'temporary' code, saving under a different name is easy.
