Have you had experience working with the global flask.g object in your projects?

flask.g is a global object in Flask used to store data specific to the current request. It exists only within the context of a single request and allows convenient passing of information between functions and handlers without using global variables.

For example, you can store a database connection in flask.g to use it in different parts of the handler:

from flask import Flask, g
import sqlite3

app = Flask(__name__)

def get_db():
    if 'db' not in g:
        g.db = sqlite3.connect('database.db')
    return g.db

@app.route('/')
def index():
    db = get_db()
    # use db for queries
    return 'Hello'

@app.teardown_appcontext
def close_db(exception):
    db = g.pop('db', None)
    if db is not None:
        db.close()

Thus, flask.g helps store and manage resources related to the current request.
