新手求教pycharm python代码连接mysql报错？

Question

Navicat和pycharm的DB Browser 可以打开这个数据库。

import pymysql
db = pymysql.connect(host=“localhost”,port=3306,user=“root”,password=“root”,database=“csdn_crawler”)
cursor = db.cursor()
cursor.execute(“select * from article”)
result = cursor.fetchone()
print(result)
运行后报错：Traceback (most recent call last):
File “D:\python_work\python爬虫\四、数据存储\04MySQL数据库操作\01-连数据库.py”, line 1, in

同萌新，回答提问，你安装mysql的客户端了么？检测MySQL服务是否启动，账号，密码是否正确
