I am currently deploying a Flask app to AWS Beanstalk, and I am trying to log out some stuff in the application (print), but I am not sure how to view it within Beanstalk, do guide me along, thank you!

The print should be in /var/log/web.output.log. However, they can show up with a delay. Thus, I found that its easier to hook up into gunicorn logger from flask which update web.output.log in real time.
Below is sample application.py that you can test it out and see how to set it up:
import os
from flask import Flask, Blueprint
from flask_restful import Api
from datetime import datetime
import logging
application = Flask(__name__)
@application.route("/")
def hello():
current_time = datetime.now().strftime("%H:%M:%S")
print(f"print from the app {current_time}")
application.logger.info(f"info from hello {current_time}")
application.logger.error(f"error from hello {current_time}")
return "<h1 style='color:blue'>Hello There!</h1>"
if __name__ == '__main__':
application.run()
else:
gunicorn_logger = logging.getLogger('gunicorn.error')
application.logger.handlers = gunicorn_logger.handlers
application.logger.setLevel(logging.INFO)
