has-flag 0.1.1

Check if argv has a specific flag

has-flag

Check if argv has a specific flag.

This is a port of the Node.js package has-flag to Python.

Install

python3 -m pip install -U has-flag

(That strange-looking setup command is because I've found it to be the most reliable. The pip command often aliases to python 2, and pip3 often installs to the wrong Python package directory.)

Usage

from has_flag import has_flag

has_flag('unicorn');
#>>> True

has_flag('--unicorn');
#>>> True

has_flag('f');
#>>> True

has_flag('-f');
#>>> True

has_flag('foo=bar');
#>>> True

has_flag('foo');
#>>> False

has_flag('rainbow');
#>>> False

$ python3 foo.py -f --unicorn --foo=bar -- --rainbow
