如何从我的python应用程序在SQLite数据库中存储用户I和密码？

import sqlite3

conn = sqlite3.connect('database.db')

cursor = conn.cursor()

cursor.execute('''CREATE TABLE IF NOT EXISTS users
                  (id INTEGER PRIMARY KEY AUTOINCREMENT,
                   username TEXT NOT NULL,
                   password TEXT NOT NULL)''')

username = 'example_user'
password = 'example_password'
cursor.execute("INSERT INTO users (username, password) VALUES (?, ?)", (username, password))

conn.commit()
conn.close()
