[已解决]问一下，这段程序为什么在我这一直报错？（新手）

李伦奥

from Tkinter import *

master = Tk()

frame = Frame(master)
frame.pack(padx=10,pady=10)

v1 = StringVar()
v2 = StringVar()
v3 = StringVar()

def test(content):
    return content.isdigit()   

testCMD = master.register(test)

e1 = Entry(frame,textvariable=v1,validate="key",validatecommand=(testCMD,"%P")).grid(row=0,column=0)
Label(frame,text="+").grid(row=0,column=1)
e2 = Entry(frame,textvariable=v2,validate="key",validatecommand=(testCMD,"%P")).grid(row=0,column=2)
Label(frame,text="=").grid(row=0,column=3)
e3 = Entry(frame,textvariable=v3,state="readonly").grid(row=0,column=4)

def calc():
    result = int(v1.get())+int(v2.get())
    v3.set(str(result))
   
Button(frame,text="计算结果",command=calc).grid(row=1,column=2,pady=5)

mainloop()

from tkinter import * # 这里

frame.pack(padx=10,pady=10)

    return content.isdigit()   

testCMD = master.register(test)

e1 = Entry(frame,textvariable=v1,validate="key",validatecommand=(testCMD,"%P")).grid(row=0,column=0)
Label(frame,text="+").grid(row=0,column=1)
e2 = Entry(frame,textvariable=v2,validate="key",validatecommand=(testCMD,"%P")).grid(row=0,column=2)
