IPython

IPython is an interactive shell for Python.

IPython used to encapsulate both the back-end shell and the front-end web-based notebook, but the notebook functionality has since migrated to its own project, Jupyter. See Jupyter for notebook-specific stuff.

Installation from Source (Old Instructions)

Building it

Version 1.12

Download the latest version here: http://archive.ipython.org/release/

Unzip it:

$ tar xzf ipython-1.12.0.tar.gz -C ~/pkg/_sources/

Build it and install it, being sure to point it to the correct version of Python:

$ python setup.py build

$ python setup.py install --prefix=${HOME}/pkg/ipython/1.12.0

make it the standard version:

$ ln -fs ${HOME}/pkg/ipython/{1.12.0,std}

iPython will make its own executable, instead of running "python" you run "ipython". Put the ipython command in $PATH and $PYTHONPATH by putting this in your favorite dot file:

export PATH="${HOME}/pkg/ipython/std/bin:${PATH}"

export PYTHONPATH="${HOME}/pkg/ipython/std/lib/python2.7/site-packages

Testing your build

Once you've done all of this, you should be able to issue the command and see the prompt:

$ ipython
