window.title("My Calculator")
#버튼 입력 함수 설정
def click():
display.insert(0, button_array[i,j])
#계산 결과 표시할 위치
display = Entry(window, width=33, bg="yellow")
display.grid(row=0, column=0, columnspan=5)
#버튼 리스트로 만든 뒤 array 형태로 변경
button_list = [
'7','8','9','/','C',
'4','5','6','*',' ',
'1','2','3','-',' ',
'0','.','=','+',' ']
button_array = np.array(button_list).reshape(4,5)
for i in range(4):
for j in range(5):
b = Button(window, text=button_array[i,j], width=5, command=click)

What you can do is set a StringVar object, as set it as the display's "textvariable" attribute (when creating the display).
Then on each change of the text, use the set method of the StringVar to change the text.
Try looking at this example
Good Luck,
Dan
