arrow keys in interpreter ^[[D

In 2.7.10 the arrow keys work normally

In 2.7.11 left gives ^[[D

In 2.7.13 left gives ^[[D

Tried various terminal setups in putty and from a nomachine session and from an xterm. Host is centos7. all 3 version are installed on the same machine.

Up arrow gives ^[[A which makes it annoying to retype a whole line for a simple typo.

Arrow keys require the

Arrow keys require the readline library, which is GPL. The simplest solution is to use python from anaconda + intel libraries for everything else:

conda remove --force python

conda install -c anaconda python

kgore4,

In case you move to IPython, make sure you read this post because readline is also GPL. Just in case...

A workaround to resolve the arrow key issue (tested under linux sh shell) is to start python preceded by 'rlwrap' like so:

$ rlwrap python

This can be written as an alias in the ".bashrc" file

Try

pip install gnureadline

instead just readline

Update for this older thread:

Our Linux python 3 distribution now includes pyeditline, a python package that implements much of the readline functionality on top of the editline library. You should see normal command-line editing features in python 3 on linux. We don't plan on adding it to our python 2.7 distribution at this time because pyeditline does not support python 2.

You can install it into an existing python 3 environment using "conda install pyeditline -c intel".
