无法将 Python 连接到 MySQL

Question

I'm using pycharm 2017 and SQL Server 2019 and my problem is I use this code:

import mysql.connector

cnx = mysql.connector.connect(user='sa', password='pooria1376',
                              host='localhost',
                              database='pooriadb')
cnx.close()

I see this error:

C:\Python34\python.exe C:/Users/LA/PycharmProjects/untitled/main
Traceback (most recent call last):
  File "C:\Python34\lib\site-packages\mysql\connector\network.py", line 509, in open_connection
    self.sock.connect(sockaddr)
ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:/Users/LA/PycharmProjects/untitled/main", line 5, in <module>
    database='pooriadb')
  File "C:\Python34\lib\site-packages\mysql\connector\__init__.py", line 179, in connect
    return MySQLConnection(*args, **kwargs)

    self._socket.open_connection()

    errno=2003, values=(self.get_address(), _strioerror(err)))
mysql.connector.errors.InterfaceError: 2003: Can't connect to MySQL server on 'localhost:3306' (10061 No connection could be made because the target machine actively refused it)

Process finished with exit code 1

Also I disabled firewall, "sa" is default username of SQL Server and I'm sure my password is true (because I login with this information). Anyone can please help me?
