A Python library that reformats exception tracebacks into readable, colorized output. It can be installed globally via the Python startup procedure or imported per-project, with configurable display options.

Use cases

• make python tracebacks easier to read
• colorize python exception output in the terminal
• show local variables in stack traces
• filter stack trace frames by path whitelist or blacklist
• prettify errors when a framework overrides stderr

When to choose

• you want clearer, colorized tracebacks for CLI scripts or development
• you want a one-line global setup via python startup
• you need configurable traceback display like line numbers and local variables

When to avoid

• you need structured machine-readable error logs for production monitoring
• your environment has no color terminal support and you dislike monochrome output
• you rely on frameworks that fully control exception handling and cannot use excepthook
