Question

我想使用Python在笔记本电脑中选择的数据库中存储检索到的数据吗？

有任何设置和连接吗？

我做过：

pip install mysql.connector

以下情况：Python MySQL - CodersLegacy [^]

我尝试过：

import mysql.connector
 
check = mysql.connector.connect(
    host= 'localhost',
    user = 'root',
    password = '12345678')
 
print(check)

它给我错误：

问题可能是因为您的连接器未指定要连接的数据库的名称。该代码可以正常工作，否则也可以尝试。例如：

mydb = mysql.connector.connect(
  host="localhost",
  user="root",
  passwd="12345678", 
  database="name_of_your_database"
)
print(mydb)

运行SQL，无法进入
