Question

我是python的新手，我在mysql网站上使用python 3.6和mysql连接器

pip install --allow-external mysql-connector-python mysql-connector-python

一切都很顺利。我试过mysql网站的3个例子创建数据库和表，插入，选择。

但是在第二个例子后它停止工作并发出错误

Traceback (most recent call last):
  File "select.py", line 3, in <module>
    import mysql.connector
  File "C:\Users\preet\AppData\Local\Programs\Python\Python36\lib\site-packages\

    cnx = mysql.connector.connect(user='root', password='Jinqm21k',
AttributeError: module 'mysql' has no attribute 'connector'

示例代码

from __future__ import print_function
from datetime import date, datetime, timedelta
import mysql.connector



cnx = mysql.connector.connect(user='root', password='Jinqm21k',
                              host='localhost',
                              database='worpress')
cursor = cnx.cursor()                             

query = ("SELECT first_name, last_name, hire_date FROM employees "
         "WHERE hire_date BETWEEN %s AND %s")

hire_start = datetime.date(1999, 1, 1)
hire_end = datetime.date(1999, 12, 31)

cursor.execute(query, (hire_start, hire_end))

for (first_name, last_name, hire_date) in cursor:
  print("{}, {} was hired on {:%d %b %Y}".format(
    last_name, first_name, hire_date))


cursor.close()  
cnx.close()

所有示例都停止工作，包括创建，插入，选择

我无法弄清楚它有什么问题

您的问题是mysql库试图导入一些导入“select”包的软件包，该软件包被模块“select.py”遮蔽。在重命名“select.py”之后，请提供更新后的回溯。

我还建议您不在.py文件中编写代码，除非您希望在模块导入时执行此代码。请改为创建例程，并在__main__部分调用它。

from __future__ import print_function
from datetime import date, datetime, timedelta
import mysql.connector

def print_employees():
    cnx = mysql.connector.connect(user='root', password='Jinqm21k',
                              host='localhost',
                              database='worpress')
    cursor = cnx.cursor()
    ...

if __name__ = '__main__':
    print_employees()

Python - AttributeError：模块'mysql'没有属性'connector'
