python-mysqlHow can I use Python and MySQL to create a login system?

Using Python and MySQL, you can create a login system that allows users to securely log in and access content. Here is an example of how to create a login system using Python and MySQL:

# Import the necessary packages
import mysql.connector

# Connect to the database
mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  passwd="yourpassword",
  database="mydatabase"
)

mycursor = mydb.cursor()

# Create a table for user accounts
mycursor.execute("CREATE TABLE users (username VARCHAR(255), password VARCHAR(255))")

# Insert a user into the table
sql = "INSERT INTO users (username, password) VALUES (%s, %s)"
val = ("John", "password123")
mycursor.execute(sql, val)

mydb.commit()

print(mycursor.rowcount, "record inserted.")

Output example

1 record inserted.

1. Import the necessary packages - imports the mysql.connector package to use for connecting to the database.
2. Connect to the database - connects to the database using the host, user, password, and database information.
