How to repeat last command in python interpreter shell?

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.

I use the following to enable history on python shell.

This is my .pythonstartup file . PYTHONSTARTUP environment variable is set to this file path.

# python startup file import readline import rlcompleter import atexit import os # tab completion readline.parse_and_bind('tab: complete') # history file histfile = os.path.join(os.environ['HOME'], '.pythonhistory') try:     readline.read_history_file(histfile) except IOError:     pass atexit.register(readline.write_history_file, histfile) del os, histfile, readline, rlcompleter

You will need to have the modules readline, rlcompleter to enable this.

Check out the info on this at : http://docs.python.org/using/cmdline.html#envvar-PYTHONSTARTUP.

Modules required:

1. http://docs.python.org/library/readline.html
2. http://docs.python.org/library/rlcompleter.html

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.
