ipython [options] [files...]

ipython (Interactive Python) is an enhanced Python shell that extends the standard interpreter with features designed for productive exploratory programming. It provides automatic syntax highlighting, comprehensive tab completion for objects, modules, and file paths, inline docstring access with `?` and `??` suffixes, and a searchable input history that persists across sessions.A distinguishing feature is IPython's system of magic commands -- special directives prefixed with `%` (line magics) or `%%` (cell magics) -- that provide functionality outside of normal Python syntax, such as `%timeit` for benchmarking, `%run` for executing scripts, `%debug` for post-mortem debugging, and `%paste` for correctly handling indented code from the clipboard. IPython also integrates tightly with the scientific Python ecosystem, offering optional auto-import of NumPy and Matplotlib via `--pylab`, and serves as the default kernel for Jupyter notebooks.

Heavier than standard Python. Magic commands are not valid Python syntax. Profile configuration may need migration between major versions. The ipython notebook subcommand was removed; use jupyter notebook instead.

IPython was created by Fernando Perez in 2001 to improve Python's interactive experience. It evolved into the Jupyter project, with IPython remaining as the Python kernel. It became essential infrastructure for scientific Python.
