How to repeat last command in python interpreter s

Question

How do I repeat the last command? The usual keys: Up, Ctrl+Up, Alt-p don't work. They produce nonsensical characters.

Answer 1

This can happen when you run python script.py vs just python to enter the interactive shell, among other reasons for readline being disabled.

Try:

import readline

Answer 2

Alt + p for previous command from histroy, Alt + n for next command from history.

This is default configure, and you can change these key shortcut at your preference from Options -> Configure IDLE.

Answer 3

Using arrow keys to go to the start of the command and hitting enter copies it as the current command.

Then just hit enter to run it again.

Answer 4

Up arrow works for me too. And i don't think you need to install the Readline module for python builtin commandline. U should try Ipython to check. Or maybe it's the problem of your keybord map.

Answer 5

In IDLE, go to Options -> Configure IDLE -> Keys and there select history-next and then history-previous to change the keys.

Then click on Get New Keys for Selection and you are ready to choose whatever key combination you want.

Answer 6

In my mac os python3 you can use: control+p early command contrlo+n next command
