python标准对话框

帅到没朋友

我的python安装的是3.7版本的，按照小甲鱼老师标准对话框那节课，我试着敲代码，最后显示有错误，求大神指教下。谢谢！
----------------------------------------------------------------------
from tkinter import *

root = Tk()

def callback():
    fileName = colorchooser.askcolor()
    print(fileName)


Button(root, text='选择颜色', command=callback).pack()


mainloop()
--------------------------------------------------------------------
错误提示如下：
Exception in Tkinter callback
Traceback (most recent call last):
  File "D:\Pathon软件\Pathon\lib\tkinter\__init__.py", line 1705, in __call__
    return self.func(*args)
  File "C:\Users\Johnny Xu\Desktop\Python文件\标准对话框.py", line 6, in callback
    fileName = colorchooser.askcolor()
NameError: name 'colorchooser' is not defined
