如何修复 Tkinter 标签不出现？

Question

我正在 Tkinter 中制作游戏。一个动态的点击游戏，你必须购买你“点击”的东西。我一直在尝试启动库存屏幕，但遇到了一个我无法理解的问题。当玩家通过单击按钮打开“库存”屏幕时，会出现一个窗口，其中包含他们拥有的所有水果（例如，苹果：654（测试编号））。但由于某种原因，什么都没有出现。完全没有。没有错误，也没有标签。这是为什么呢？

代码：

from tkinter import *

money = 0
currentfruit = "Apple"
numOfApples = 654

def clicked():
    global money
    global currentfruit
    if currentfruit == "Apple":
        money = money + 1
    moneystringvar.set("You have $" + str(money))
    if money < 10:
        moneylabel.place(x="327", y="0")
    if money < 100 and money > 9:
        moneylabel.place(x="320", y="0")
    if money < 1000 and money > 99:
        moneylabel.place(x="315", y="0")

def inventoryOnClose():
    root.deiconify()
    inventorywindow.destroy()

def marketOnClose():
    root.deiconify()
    marketwindow.destroy()

def upgradesOnClose():
    root.deiconify()
    upgradeswindow.destroy()

def inventory():
    global inventorywindow
    global numOfApples
    root.withdraw()
    inventorywindow = Tk()
    inventorywindow.title("Fruit Clicker - Inventory")
    inventorywindow.geometry("400x350+300+100")
    inventorywindow.protocol("WM_DELETE_WINDOW", inventoryOnClose)
    applesinventory = StringVar()
    applesinventory.set("Apples: " + str(numOfApples))
    applesinvlabel = Label(inventorywindow, textvariable=applesinventory)
    applesinvlabel.place(x="0", y="0")
    inventorywindow.mainloop()

def market():
    global marketwindow
    root.withdraw()
    marketwindow = Tk()
    marketwindow.title("Fruit Clicker - Market")
    marketwindow.geometry("400x350+300+100")
    marketwindow.protocol("WM_DELETE_WINDOW", marketOnClose)
    marketwindow.mainloop()

def upgrades():
    global upgradeswindow
    root.withdraw()
    upgradeswindow = Tk()
    upgradeswindow.title("Fruit Clicker - Upgrades")
    upgradeswindow.geometry("400x350+300+100")
    upgradeswindow.protocol("WM_DELETE_WINDOW", upgradesOnClose)
    upgradeswindow.mainloop()

root = Tk()
root.title("Fruit Clicker")
root.geometry("400x350+300+100")

inventorybutton = Button(root, text="Inventory", fg="White", bg="Black", width="6", command=inventory)
inventorybutton.grid(column="0", row="0")

marketbutton = Button(root, text="Market", fg="White", bg="Black", width="6", command=market)
marketbutton.grid(column="0", row="1")

upgradesbutton = Button(root, text="Upgrades", fg="White", bg="Black", width="6", command=upgrades)
upgradesbutton.grid(column="0", row="2")

leftfruitbutton = Button(root, text="<")
leftfruitbutton.place(x="100", y="285")

currentfruitstringvar = StringVar()
if currentfruit == "Apple":  
    currentfruitstringvar.set("Apple x" + str(numOfApples))
    currentfruitlabel = Label(root, textvariable=currentfruitstringvar, fg="Black")
    if numOfApples < 10:
        currentfruitlabel.place(x="180", y="290")
    if numOfApples < 100 and numOfApples > 9:
        currentfruitlabel.place(x="175", y="290")
    if numOfApples < 1000 and numOfApples > 99:
        currentfruitlabel.place(x="170", y="290")

rightfruitbutton = Button(root, text=">")
rightfruitbutton.place(x="287", y="285")

moneystringvar = StringVar()
moneystringvar.set("You have $" + str(money))
moneylabel = Label(root, textvariable=moneystringvar)
if money < 10:
    moneylabel.place(x="327", y="0")
if money < 100 and money > 9:
    moneylabel.place(x="320", y="0")
if money < 1000 and money > 99:
    moneylabel.place(x="315", y="0")

clickerphoto = PhotoImage(file = "apple.png")
clickerbutton = Button(root, text="Clicker Button", image=clickerphoto, fg="Black", command=clicked)
clickerbutton.place(x="100", y="75")

root.mainloop()

我不确定你是否需要 apple.png，但如果你需要，这里是我的 GitHub 存储库的链接：https://github.com/SeaPuppy2006/FruitClicker

谢谢！

对于原始 Tk() 窗口的所有子窗口，它应该是 upgradeswindow = Toplevel()，而不是 upgradeswindow = Tk()。
