bpython - a fancy {curtsies, curses, urwid} interface to the Python interactive interpreter

bpython [options] [file [args]]

bpython-curses [options] [file [args]]

bpython-urwid [options] [file [args]]

The idea is to provide the user with all the features in-line, much like modern IDEs, but in a simple, lightweight package that can be run in a terminal window.

Hilights commands as you type!
Press tab to complete expressions when there's only one suggestion.
This displays a list of parameters for any function you call. It uses the inspect module, then tries pydoc.
This is a bit misleading, but it code that has been entered is remembered, and when you Rewind, it pops the last line and re-evaluates the entire code. This is error-prone, and mostly useful for defining classes and functions.
This posts the current buffer to a pastebin (bpaste.net) or writes it to a file.
Unlike other curses apps, bpython dumps the screen data to stdout when you quit, so you see what you've done in the buffer of your terminal.

The long and short forms of options, shown here as alternatives, are equivalent. If bpython sees an argument it does not know, execution falls back to the regular Python interpreter.

The following options are supported by all frontends:

Use <config> instead of default config file.
Show the help message and exit.
Drop to bpython shell after running file instead of exiting. The PYTHONSTARTUP file is not read.
Do not flush the output to stdout.
Print bpython's version and exit.

In addition to the above options, bpython also supports the following options:

Write debugging messages to the file bpython.log. Use -LL for more verbose logging.
Paste in the contents of a file at startup.

In addition to the common options, bpython-urwid also supports the following options if Twisted is available:

Use Twisted's <reactor> instead of urwid's event loop.
Display a list of available Twisted reactors.
Execute a twistd plugin. Use twistd to get a list of available plugins. Use -- to pass options to the plugin.
Run an eval server on port <port>. This option forces the use of a Twisted reactor.

bpython's keys are fully configurable. See http://docs.bpython-interpreter.org/configuration.html#keyboard

$XDG_CONFIG_HOME/bpython/config

Your bpython config. See sample-config (in /usr/share/doc/bpython/examples on Debian) for various options you can use, or read bpython-config(5).

See http://github.com/bpython/bpython/issues/ for a list of known issues.
