Suppose you have the above, as you indicated. Ctl-P your way back to the a=10 line. Press Ctl-O. It executes that assignment and fills the input buffer with "a-=1". Instead of just pressing Ctl-O, type a "1" first, changing the input buffer to "a-=11". *Now* press Ctl-O. I assume it executes that statement. You've edited the line, however. Does it present you with the print statement or not? I guess I could have answered my own question using bash: firefly% a=10 firefly% a='a' firefly% echo $a a firefly% a=10 firefly% a='b' firefly% echo $a b The second batch of three lines were executed from history with this key sequence: Ctl-P Ctl-P Ctl-P Ctl-O DEL DEL b ' Ctl-O RET That's pretty cool. Even if I never live to see it in Python (I'm still using 2.7), I will definitely start using it in bash. :-) Skip -- https://mail.python.org/mailman/listinfo/python-list
