我是 Python 和 Tkinter 的新手，我正在嘗試制作一個視窗，它有一個按鈕，按下按鈕時，會在新視窗中打開計算器的代碼，我已經準備好計算器代碼并且它可以獨立作業，但是當我復制了它并試圖讓它與新視窗一起作業，它只是打開一個空視窗。
打開新視窗代碼來自本教程：Open a new Window with a button in Python-Tkinter。
計算器是由 FreeCodeCamp.org 的 tkinter 課程制作的，它包含了很多代碼e.get，認為這是我將其更改為 的問題newWindow。
from tkinter import *
from tkinter.ttk import *
master = Tk()
master.geometry("200x200")
def openNewWindow():
global newWindow
newWindow = Toplevel(master)
newWindow.title("New Window")
newWindow = Entry(width=35, borderwidth=5)
newWindow.grid(row=0, column=0, columnspan=3, padx=10, pady=10)
def button_click(number):
current = newWindow.get()
newWindow.delete(0, END)
newWindow.insert(0, str(current) str(number))
def button_clear():
newWindow.delete(0, END)
def button_add():
first_number = newWindow.get()
global f_num
global math
math = "addition"
f_num = int(first_number)
newWindow.delete(0, END)
def button_equal():
second_number = newWindow.get()
newWindow.delete(0, END)
if math == "addition":
newWindow.insert(0, f_num int(second_number))
if math == "subtraction":
newWindow.insert(0, f_num - int(second_number))
if math == "multiplication":
newWindow.insert(0, f_num * int(second_number))
if math == "devision":
newWindow.insert(0, f_num / int(second_number))
def button_subtract():
first_number = newWindowe.get()
global f_num
global math

f_num = int(first_number)
newWindow.delete(0, END)

運行代碼時觀察終端。當視窗停止回應時，通常意味著python遇到錯誤并在終端中列印出來。看起來您仍然需要做一些作業來將您的代碼從獨立遷移過來 -root沒有在任何地方定義。我也洗掉了from tkinter.ttk import *它為我擺脫了一堆未知的選項錯誤。

沒有真正做整件事（雖然我做了并且我學到了一些東西），這是一個骨架：
def openNewWindow():
# Toplevel window uses pack manager, not grid manager
newWindow = Toplevel(master)
newWindow.title(...)
# Create a frame as the only object in Toplevel.
# The frame will contain the other objects and use the grid manager.
frame = Frame(newWindow)
frame.pack()
# Create items in the frame and grid them
entry = Entry(frame, width=35)
entry.grid(row=0, ...)
button_1 = Button(frame, text="1", command=...)
button_1.grid(row=3, column=0, padx=4, pady=2)
button_2 = Button(...)
button_2.grid(...)
...
用于操作文本輸入框的內容：
entry.get()
entry.delete(0, END)
entry.insert(0, str)
