This code work for me

        import pymysql
        import paramiko
        from paramiko import SSHClient
        from sshtunnel import SSHTunnelForwarder
        from sqlalchemy import create_engine

        #ssh config
        mypkey = paramiko.RSAKey.from_private_key_file('your/user/location/.ssh/id_rsa')             
        ssh_host = 'your_ssh_host'
        ssh_user = 'ssh_host_username'
        ssh_port = 22  

        #mysql config         
        sql_hostname = 'your_mysql_host name'
        sql_username = 'mysql_user'
        sql_password = 'mysql_password'
        sql_main_database = 'your_database_name'
        sql_port = 3306
        host = '127.0.0.1'



        with SSHTunnelForwarder(
                (ssh_host, ssh_port),
                ssh_username=ssh_user,
                ssh_pkey=mypkey,
                remote_bind_address=(sql_hostname, sql_port)) as tunnel:              

            engine = create_engine('mysql+pymysql://'+sql_username+':'+sql_password+'@'+host+':'+str(tunnel.local_bind_port)+'/'+sql_main_database)
            connection = engine.connect()
            print('engine creating...')
            sql = text(""" select * from nurse_profiles np limit 50""")
            nurseData = connection.execute(sql)
            connection.close()


            nurseList = []
            for row in nurseData:
                nurseList.append(dict(row))
            print('nurseList len: ', len(nurseList))
            print('nurseList: ', nurseList)
