[已解决]python报错

咋回事呀？

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python37-32\lib\tkinter\__init__.py", line 1702, in __call__
    return self.func(*args)
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python37-32\Lib\site-packages\program\tool.py", line 36, in explorer
    button = tk.Button(frame, text="确定", command=Yes)
UnboundLocalError: local variable 'Yes' referenced before assignment

相关代码：

def explorer(self):
        root = tk.Tk()
        frame = tk.Frame(root)
        frame.pack()

        e = tk.Entry(root)
        e.pack(padx=20, pady=20)

        button = tk.Button(frame, text="确定", command=Yes)
        button.pack()

        def Yes():
            os.startfile(e.get())

        root.geometry()

        root.title("请输入路径:")
        
        mainloop()
