运行 SQL, 进不去
Running SQL, cannot get into
我想使用 Python?
将检索到的数据存储在笔记本电脑中我选择的数据库中
有没有设置和连接?
我做过:
pip install mysql.connector
以下:Python MySQL - CodersLegacy[^]
我试过之后:
import mysql.connector
check = mysql.connector.connect(
host= 'localhost',
user = 'root',
password = '12345678')
print(check)
它给我错误:
---------------------------------------------------------------------------
InterfaceError Traceback (most recent call last)
<ipython-input-4-e72118a94c51> in <module>()
3 check = mysql.connector.connect(

问题可能是因为您的连接器没有指定您要连接的数据库的名称。该代码在其他方面也能正常工作,但您可能想尝试一下。
例如:
mydb = mysql.connector.connect(
host="localhost",
user="root",
passwd="12345678",
database="name_of_your_database"
)
print(mydb)
