Python - not able to push file line no and file path to Google Cloud StackDriver

Question

I have the following to send logging messages to stackdriver :

logger.py

import google.cloud.logging
import os
import logging
import sys

logging.basicConfig(level=logging.INFO, format="[VREPORT_LOG] [%(asctime)s] [%(pathname)s:%(lineno)d] %(message)s",datefmt="%H:%M:%S", stream=sys.stdout)
if (os.environ.get("PYTHON_ENV") != "local"):
    client = google.cloud.logging.Client()
    client.setup_logging()

def use_logging_handler():
    logging.info("Initialising logger...")

if __name__ == '__main__':
    use_logging_handler()

server.py

from utilities.logger import use_logging_handler
use_logging_handler()
...
logging.info("test")
logging.info("test1")

This is what happens on the server terminal

[09:35:33] [server.py:2322] test
test
[09:35:33] [server.py:2323] test1
test1

This is what was logged to the cloud

I 2019-08-20T09:35:33.831234Z test1 
I 2019-08-20T09:35:33.830988Z test 

I also have to call use_logging_handler() in every function if I want to log something which is very inconvenient. If I put use_logging_handler() at the start of a file, it would log print() statements as well which is very annoying. How can I log the file name and line number to the cloud and without having to call use_logging_handler() in every function (something similar to Winston in NodeJS )?

You need to configure the logging handler

To write log entries , first create a Logger, passing the “log name” with which to associate the entries:

logger = client.logger(LOG_NAME)
