簡介

A library for automatically generating command line interfaces.

Python Fire is a library for automatically generating command line interfaces (CLIs) with a single line of code.

It will turn any Python module, class, object, function, etc. (any Python component will work!) into a CLI. It’s called Fire because when you call Fire(), it fires off your command.
