Repeat last n commands

[Julius Hamilton]

Hey,

Sometimes I am writing a method in a live Python shell (respectively in
Termux, which uses Bash) and I make a mistake and the method definition is
cancelled and I'd like to redo all executed lines up to the erroneous one.

I believe that the ability to re-execute the last n lines would be part of
bash rather than Python, is that correct?

Is there any such command?

Thanks very much,
Julius
