我根据网上资料制作了一个可以随机生成编号的小工具，界面如下。
初步完成后想要重构一下，以便后续增加内容。但在重构过程中遇到一个问题，就是在生成编号的函数中需要调用tkinter的delete和insert方法，如
entry_vin.delete(0, "end")
entry_vin.insert("end", vin)
text_vin.insert(tk.END, vin + '\n')
而在定义按钮时，又需要调用生成编号的函数名creat_vin
btn1 = tk.Button(root,text='生成VIN码',command=creat_vin)
这样相互调用就不知道该怎么写了，陷入了死循环，希望有大手子可以帮忙指导下重构或者写代码的思路，感激不尽！代码在下面。
