Python用openpyxl首句就报错，啥原因

import openpyxl
from openpyxl import load_workbook
wb = Workbook()
这是代码
C:\python\python.exe D:/xuexi/123.py
Traceback (most recent call last):
File "D:/xuexi/123.py", line 3, in
wb = Workbook()
NameError: name 'Workbook' is not defined
下面报错，显示Workbook未定义

开头直接这样写
from openpyxl import *
后面就会方便一点
或者
from openpyxl import Workbook

如果有用，希望点击右上角给个采纳哦~

还需要导入：
from openpyxl import Workbook
