ptpython3

Enhanced interactive Python 3 REPL

TLDR

Start Python 3 REPL

$ ptpython3

Start with vi mode

$ ptpython3 --vi

Execute file then REPL

$ ptpython3 -i [script.py]

ptpython3 is the Python 3 variant of ptpython, an enhanced interactive REPL with syntax highlighting, autocompletion, multi-line editing, and vi/emacs key bindings built on the prompt_toolkit library.On modern systems where Python 3 is the default, ptpython and ptpython3 are typically identical. The separate binary exists for systems where both Python 2 and Python 3 are installed side by side.

PARAMETERS

FILE

Python file to execute before entering the REPL.

--vi

Use Vi key bindings instead of the default Emacs bindings.

-i, --interactive

Drop into an interactive REPL after executing FILE.

--asyncio

Run an asyncio event loop so top-level await expressions work.

--light-bg

Use a color scheme tuned for terminals with a light background.

--dark-bg

Use a color scheme tuned for terminals with a dark background.

--config-file PATH

Load configuration from a non-default file.

--history-file PATH

Use the specified file for input history.

-V, --version

Display version information.

CONFIGURATION

$PTPYTHON_CONFIG_HOME

Override the directory ptpython searches for its configuration. Defaults to a platform-specific user config directory (e.g. ~/.config/ptpython/ on Linux).

$PYTHONSTARTUP

Standard Python variable; the referenced file runs before the interactive prompt.

CAVEATS

Python 3 variant of ptpython; on modern systems where Python 3 is the default the two binaries are equivalent. Configuration files are honored only when ptpython is launched directly — not when embedded inside another application.
