app.py

import logging

from flask import Flask, request
from flask.logging import default_handler


class RequestFormatter(logging.Formatter):
    def format(self, record):
        record.url = request.url
        record.remote_addr = request.remote_addr
        return super().format(record)


app = Flask(__name__)

formatter = RequestFormatter(
    '[%(asctime)s] %(remote_addr)s requested %(url)s\n'
    '%(levelname)s in %(module)s: %(message)s'
)

default_handler.setFormatter(formatter)


@app.route("/")
def hello():
    return "Hello World!"


if __name__ == "__main__":
    app.run()
