Set up Python SDK

Install and initialize the LaunchDarkly Python SDK

Install the package

pip3 install launchdarkly-server-sdk

Initialize the SDK

import os
import ldclient
from ldclient import Context
from ldclient.config import Config

if __name__ == '__main__':
    # Set your LaunchDarkly SDK key.
    # This is inlined as example only for onboarding.
    # Never hardcode your SDK key in production.
    ldclient.set_config(Config('YOUR_SDK_KEY'))

    if not ldclient.get().is_initialized():
        print('SDK failed to initialize')
        exit()

    # For onboarding purposes only we flush events as soon as
    # possible so we quickly detect your connection.
    # You don't have to do this in practice because events are automatically flushed.
    ldclient.get().flush()
    print('SDK successfully initialized')
