Welcome to IPython. Our full documentation is available on ipython.readthedocs.io and contain information on how to install, use contribute to the project.
Officially, IPython requires Python version 2.7, or 3.3 and above. IPython 1.x is the last IPython version to support Python 2.6 and 3.2.
The Notebook, Qt console and a number of other pieces are now parts of Jupyter. See the Jupyter installation docs if you want to use these.
You can find the latest version of the development documentation on readthedocs.
You can run IPython from this directory without even installing it system-wide by typing at the terminal:
$ python -m IPython
Or see the developement installation docs for the latest revision on read the docs.
Documentation and installation instructions for older version of IPython can be found on the IPython website
