SYNOPSIS

ipython3 [options] [file] [args]

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
%debug             Enter debugger
%history           Show history
%paste             Paste from clipboard
%cd                Change directory
!command           Run shell command
?object            Get help
??object           Get source code

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.
