我是python的新手，我在mysql网站上使用python3.6和mysql连接器

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

一切都很顺利。我尝试了mysql网站的3个例子，创建db和table，insert，select。
但在第二个例子之后，它停止工作并给出一个错误

Traceback (most recent call last):
  File "select.py", line 3, in <module>

    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='****',
                              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create、insert和select
我想不出它有什么毛病
