Repeat last command entered in python IDLE instead of copying it

Question

Hi
when in IDLE, having a command line e.g. print("abc") and you want to repeat it at next prompt line, how can you do it?
Is there a similar function key like F3 when you are at running CMD.EXE in windows?
I tried up arrow, but it doesn' t work.

Answer 1

Not exactly what you're looking for, but can use the underscore _ to regain the result of the last operation in IDLE.
>>> 5*8
40
>>> _
40
Other than that, copy/paste is probably the only way.
