Q1. In this assignment, you will count the number of lines in a file uploaded to the GCS bucket in real-time by using Google Cloud Functions and Pub/Sub.
a. Download the file from here: https://filesamples.com/samples/document/txt/sample1.txt
b. Write a Google cloud Function which gets triggered whenever a file is added to a bucket and publishes the file name to a topic in Pub/Sub.
c. Write a python file, which acts as a subscriber to this topic and prints out the number of lines in the file in real-time.
(Documentation for pub/sub available at: https://pypi.org/project/google-cloud-pubsub/ )
Test the steps (b) and (c) using the file downloaded in step (a). Ensure that you add screenshots and share the code for all steps.
