IPython provides a rich toolkit to help you make the most out of using Python interactively. Its main components are:

• A powerful interactive Python shell
• A Jupyter kernel to work with Python code in Jupyter notebooks and other interactive frontends.

The enhanced interactive Python shells have the following main features:

• Comprehensive object introspection.
• Input history, persistent across sessions.
• Caching of output results during a session with automatically generated references.
• Extensible tab completion, with support by default for completion of python variables and keywords, filenames and function keywords.
• Extensible system of 'magic' commands for controlling the environment and performing many tasks related either to IPython or the operating system.
• A rich configuration system with easy switching between different setups (simpler than changing $PYTHONSTARTUP environment variables every time).
• Session logging and reloading.
• Extensible syntax processing for special purpose situations.
• Access to the system shell with user-extensible alias system.
• Easily embeddable in other Python programs and GUIs.
• Integrated access to the pdb debugger and the Python profiler.

The latest development version is always available from IPython's GitHub site.
