bpython is an enhanced Python REPL (Read-Eval-Print-Loop) with features like syntax highlighting, auto-completion, automatic indentation, and inline documentation. It provides a user-friendly interface for interactive Python development.
The tool improves the standard Python interactive interpreter experience with modern IDE-like features.

Not a drop-in replacement for complex scripts. Some extensions may not work. Slower startup than standard Python. Replay feature has limitations. Not suitable for production use.

bpython was created by Bob Farrell and others around 2008 to provide a more user-friendly Python REPL experience.
