召唤狮

1. from tkinter import *
   
2. root = Tk()
   
3. def callback():
   
4.      fileName = filedialog.askopenfilename()
   
5.      print(fileName)
   
6. Button(root, text="打开文件", command=callback).pack()
   
7. mainloop() #点打开文件按钮报错

复制代码

报错内容：
Exception in Tkinter callback
Traceback (most recent call last):
  File "D:\anaconda3\lib\tkinter\__init__.py", line 1883, in __call__
    return self.func(*args)
  File "<pyshell#5>", line 2, in callback
NameError: name 'filedialog' is not defined

filedialog 等一些组件在 * 导入是不被导入的，要重新进行导入

参考代码：

1. from tkinter import *
   
2. from tkinter import filedialog
   
3. 
   
4. root = Tk()
   
5. def callback():
   
6.      fileName = filedialog.askopenfilename()
   
7.      print(fileName)
   
8. Button(root, text="打开文件", command=callback).pack()
   
9. mainloop() #点打开文件按钮报错
