import mysql.connector

db = mysql.connector.connect(
    host="localhost",
    user="root",
    passwd="root",
    database="passwd",
    auth_plugin='mysql_native_password'

mainmenu()

This one is the main program and the next one is the setup.py as i said above it makes the database

import mysql.connector

db = mysql.connector.connect(
    host="localhost",
    user="root",
    passwd="root",
    database="passwd",
    auth_plugin='mysql_native_password'
)

print(db)

mycursor = db.cursor()

mycursor.execute("CREATE TABLE passwords(Website varchar(20), Username varchar(30), "
                 "Password varchar(30), Date varchar(10) not null)")

print("You have successfully created your database.")
print("You can now use the password manager.")
print("THANK YOU!")
CAN SOMEONE PLZZZ HELP ME WITH THE IMPLEMENTATION OF OOP AND CLASSES IN MY PROGRAM
I DON'T UNDERSTAND HOW TO USE IT

Two directions I can see for you to go. One is to figure out what candidates there are for classes. Making a "password" class seems overkill for that piece of data. You could make a menu class that handles the menu display and all of the activities. Or, more ambitiously, you could make a context manager that allows you to use "with" on your database. That requires you to implement __enter__ and __exit__ functions that would handle all of the opening and closing of the database connection. What are you looking for?

OOP has become a catchphrase that many equate with "structured programming". If you code is organized well and easy to use it must be OOP, right? This is completely wrong of course.
The attitude that OOP is good and all else is bad has lead to a backlash against OOP and interesting articles asking if OOP is a good choice for any problem space.

I don't seeing a password database as a good fit for OOP. The only "object" is the database, and that object is modeled by the database API. I suppose if you really dislike the mysql API you could make an object oriented wrapper.

Is this an assignment where you have to use classes to solve the problem?
