Python3.5连接pymysql出现cursor问题

Question

Ubuntu下Python3.5连接pymysql时出现错位为 with connect.cursor() as cursor:
AttributeError: 'function' object has no attribute 'cursor'
以下为代码，点击错误跳到with connect.cursor() as cursor这里，不知道为什么，弄了两天了都没弄好，求大神告诉

db = pymysql.Connect(

)

try:
with connect.cursor() as cursor:
sql="insert into pachong values (%s, %s, %s, %s, %s)"

    param=[(stock_last[0]),(stock_last[1]),(stock_last[2]),(stock_last[3]),(stock_last[4]),(stock_last[5])]
    n=cursor.executemany(sql,param)
connect.commit()

finally: print('n')
connect.close()

Answer 1

connect是一个函数，它返回的连接对象才有cursor游标

例如：

 import pymysql.cursors

#连接配置信息
config = {
          'host':'127.0.0.1',
          'port':3306,
          'user':'root',
          'password':'csdn.com',
          'db':'employees',
          'charset':'utf8mb4',
          'cursorclass':pymysql.cursors.DictCursor,
          }
# 创建连接
connection = pymysql.connect(**config)
with connection.cursor() as cursor:
...
