파이썬 Tkinter를 계산

Question

from Tkinter import *

numbers = "789456123" 
i = 0 
bttn= [] 
for k in range(1,4): 
    for k in range(3): 
     bttn.append(Button(calc, text = numbers[i])) 
     bttn[i].grid(row = j, column = k, pady = 5) 
     bttn[i]["command"] = lambda x = numbers[i]: sum1.num_press(x) 
     i += 1 

내가 파이썬 3.3를 시도했다

과 2.7 모두 후 구문 오류라고 'def_init_ (자기) :' 어떤 수정이나 뭔가가 있나요? 미리 감사드립니다.

def 사이에 공백을 추가하십시오. 특별한 초기화 방법을 지정하려면이 두 줄이 밑줄인지 확인하십시오.
