Python Fire 是 Google 开源的一个可从任何 Python 代码自动生成命令行接口（CLI）的库。Python Fire 是一种在 Python 中创建 CLI 的简单方法；是开发和调试 Python 代码的有用工具；能够使 Bash 和 Python 之间的转换更为容易；并且通过使用你需要导入和创建的模块和变量来设置 REPL，使得使用 Python REPL 更容易（详情

Python Fire is a library for automatically generating command line interfaces (CLIs) from absolutely any Python object.

• Python Fire is a simple way to create a CLI in Python. [1]
• Python Fire is a helpful tool for developing and debugging Python code. [2]
• Python Fire helps with exploring existing code or turning other people's code into a CLI. [3]
• Python Fire makes transitioning between Bash and Python easier. [4]
• Python Fire makes using a Python REPL easier by setting up the REPL with the modules and variables you'll need already imported and created. [5]

To install Python Fire with pip, run: pip install fire

To install Python Fire with conda, run: conda install fire -c conda-forge

To install Python Fire from source, first clone the repository and then run: python setup.py install

You can call Fire on any Python object:
functions, classes, modules, objects, dictionaries, lists, tuples, etc. They all work!

Here's an example of calling Fire on a class.

importfireclassCalculator(object): """A simple calculator class."""defdouble(self, number): return2*numberif__name__=='__main__': fire.Fire(Calculator)

Then, from the command line, you can run:

python calculator.py double 10 # 20 python calculator.py double --number=15 # 30

To learn how Fire behaves on functions, objects, dicts, lists, etc, and to learn about Fire's other features, see the Using a Fire CLI page.

For additional examples, see The Python Fire Guide.

When you call Fire, it fires off (executes) your command.

Please see The Python Fire Guide.

Note that flags are separated from the Fire command by an isolated -- arg.
