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. 
- Python Fire is a helpful tool for developing and debugging Python code. 
- Python Fire helps with exploring existing code or turning other people's code into a CLI. 
- Python Fire makes transitioning between Bash and Python easier. 
- 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. 
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.
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.
Why is it called Fire?
When you call
Fire, it fires off (executes) your command.
