SYNOPSIS
ipython3 [options] [file] [args]
DESCRIPTION
IPython is an enhanced interactive Python shell. It provides syntax highlighting, tab completion, magic commands, shell integration, and rich media display.IPython extends Python's REPL with features like history across sessions, object introspection, and system shell access. It's the kernel behind Jupyter notebooks.
PARAMETERS
--profile name
Use specific profile.--no-banner
Don't show startup banner.-i
Run in interactive mode after script.-c command
Execute command.--pdb
Enable automatic debugger on exceptions.--matplotlib backend
Configure matplotlib backend.qtconsole
Start Qt GUI console.notebook
Start Jupyter notebook (deprecated, use jupyter).
MAGIC COMMANDS
$ %run script.py Run Python file
%timeit expr Time execution

sudo apk add ipython
brew install ipython
CAVEATS
Separate from standard Python. Some magic commands are IPython-specific. Jupyter notebooks recommended for notebook interface.
HISTORY
IPython was created by Fernando Pérez in 2001 to improve Python's interactive capabilities. It became the foundation for Jupyter, which generalized the notebook concept to multiple languages.
