bpython is a fancy, open source, interface to the Python interpreter for Linux, BSD, OS X and Windows.
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.
bpython doesn’t seek to create anything new or groundbreaking. Instead, it brings together a few neat ideas and focuses on practicality and usefulness.
Key Features
- In-line syntax highlighting – uses Pygments for lexing the code as you type, and colours appropriately.
- Readline-like autocomplete with suggestions displayed as you type.
- Expected parameter list for any Python function – seeks to display a list of parameters for any function you call.
- “Rewind” function to pop the last line of code from memory and re-evaluate.
- Send the code you’ve entered off to a pastebin. Hit a key and what you see on the screen will be sent to a pastebin and a URL is returned for you to do what you like with. bpaste.net is used by default, but you can configure bpython to use a different pastebin.
- Save the code you’ve entered to a file.
- Auto-indentation.
- Python 3 support.
