Title

Logging example does not show output due to missing StreamHandler

Environment details

• OS type and version: macOS 12.7
• Python version: Python 3.10.13
• pip version: pip 23.2.1
• google-api-python-client version: 2.125.0

Steps to reproduce

1. Copy the logging example from https://googleapis.github.io/google-api-python-client/docs/logging.html
2. Run the script in terminal or standard Python environment
3. No log output is shown, even though logging level is set to INFO

Code example

import logging
from googleapiclient.discovery import build

logger = logging.getLogger()
logger.setLevel(logging.INFO)

def main():
    service = build('translate', 'v2', developerKey='your_api_key')
    print(service.translations().list(
        source='en',
        target='fr',
        q=['flower', 'car']
    ).execute())

if __name__ == '__main__':
    main()

Stack trace

(no output shown unless developer adds a StreamHandler manually)

Description

The logging example in the documentation sets the logging level with logger.setLevel(logging.INFO) but does not include a StreamHandler.

As a result, no output appears in most environments (e.g. terminal, script execution), unless a handler is explicitly added to send logs to stdout.

This can confuse users trying to debug API usage.

Proposed fix:

Update the example to include:

import sys
handler = logging.StreamHandler(sys.stdout)
logger.addHandler(handler)
