How to repeat last command in python interpreter shell?

Question

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

(ve)[kakarukeys@localhost ve]$ python
         


        

Answer 1

Ipython isn't allways the way... I like it pretty much, but if you try run Django shell with ipython. Something like>>>

ipython manage.py shell

it does'n work correctly if you use virtualenv. Django needs some special includes which aren't there if you start ipython, because it starts default system python, but not that virtual.

If you use Debian Jessie run this to fix your system installation 2.7.9

sudo apt-get install libncurses5-dev libncursesw5-dev

To fix my other 3.5.2 installation which I installed with pyenv :

pip install readline

Answer 3

I don't understand why there are so many long explanations about this. All you have to do is install the pyreadline package with:

pip install pyreadline

sudo  port install py-readline (on Mac)

(Assuming you have already installed PIP.)

Answer 4

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

Answer 5

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 6

For repeating the last command in python, you can use <Alt + n> in windows
