安装部署要点（README 精选）

Installation

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

Basic Usage

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 function.

import fire

def hello(name="World"):
  return "Hello %s!" % name

if __name__ == '__main__':
  fire.Fire(hello)

Then, from the command line, you can run:

python hello.py  # Hello World!
python hello.py --name=David  # Hello David!
python hello.py --help  # Shows usage information.

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

import fire

class Calculator(object):
  """A simple calculator class."""

  def double(self, number):
    return 2 * number

if __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.
