试图创建一个唯一的随机数。如果数据库中存在数字，则重新生成并向数据库添加值

import random

random_number = random.randint(1, 100)

import random
import mysql.connector

def generate_unique_random_number():
    while True:
        random_number = random.randint(1, 100)
        if not check_if_random_number_exists(random_number):
            add_random_number_to_database(random_number)
            break

def check_if_random_number_exists(random_number):
    # 连接到数据库，执行查询操作，检查随机数是否存在于数据库中
    # 这里假设使用MySQL数据库，并且已经创建了一个名为"random_numbers"的表
    connection = mysql.connector.connect(host='localhost', user='your_username', password='your_password', database='your_database')
    cursor = connection.cursor()
    query = "SELECT COUNT(*) FROM random_numbers WHERE number = %s"
    cursor.execute(query, (random_number,))
    count = cursor.fetchone()[0]
    cursor.close()
    connection.close()
    return count > 0

def add_random_number_to_database(random_number):
    # 连接到数据库，执行插入操作，将随机数添加到数据库中
    connection = mysql.connector.connect(host='localhost', user='your_username', password='your_password', database='your_database')
    cursor = connection.cursor()
    query = "INSERT INTO random_numbers (number) VALUES (%s)"
    cursor.execute(query, (random_number,))
    connection.commit()
    cursor.close()
    connection.close()
