OpenFeature SDK for Python

⚠️ Initial development is in progress, but there has not yet been a stable, usable release suitable for the public. ⚠️

This is the Python implementation of OpenFeature, a vendor-agnostic abstraction library for evaluating feature flags.

We support multiple data types for flags (numbers, strings, booleans, objects) as well as hooks, which can alter the lifecycle of a flag evaluation.

This library is intended to be used in server-side contexts and has not been evaluated for use in mobile devices.

Usage

While Boolean provides the simplest introduction, we offer a variety of flag types.

# Depending on the flag type, use one of the methods below
flag_key = "PROVIDER_FLAG"
boolean_result = open_feature_client.get_boolean_value(key=flag_key,default_value=False)
integer_result = open_feature_client.get_integer_value(key=flag_key,default_value=-1)
float_result = open_feature_client.get_float_value(key=flag_key,default_value=-1)
string_result = open_feature_client.get_string_value(key=flag_key,default_value="")
object_result = open_feature_client.get_object_value(key=flag_key,default_value={})

Each provider class may have further setup required i.e. secret keys, environment variables etc

Requirements

• Python 3.8+

Installation

Add it to your build

Pip install

pip install openfeature-sdk==0.0.9

requirements.txt

openfeature-sdk==0.0.9

pip install requirements.txt

Configure it

In order to use the sdk there is some minor configuration. Follow the script below:

from open_feature import open_feature_api
from open_feature.provider.no_op_provider import NoOpProvider

open_feature_api.set_provider(NoOpProvider())
open_feature_client = open_feature_api.get_client()

Contacting us

We hold regular meetings which you can see here.

We are also present on the #openfeature channel in the CNCF slack.
