Python3 shell 在 Linux 上按退格键打印 ^H

Question

On python3 shell launched on bash misbehaves on pressing arrows or backspace.
It prints ^H for backspace, and I can remove these characters using Ctrl+backspace or shift+backspace .
But I don't want to do this workaround for backspace (I can do, but I can't ask all my users to follow),
So how to address this issue?.
BTW, I don't see this issue in python2 shell.

Answer 1

Try stty erase ^H . If you regret, just use stty erase ^? . If you don't want to do this every time, put stty erase ^H into .bash_profile.
