Question

对于每个获奖项目，我想在GUI上显示其对应的图片。目前，我正在编写一堆在if语句中显示的代码以实现此目的。我确定我可以使用某种循环来减少代码量，但是目前还不确定如何实现。

在每次不获奖的情况下删除图像时，我也遇到问题。我当前解决此问题的尝试显示在底部else语句中提供的代码中。

chance_of_drop = random.randint(1,100)
if chance >= chance_of_drop:
    winner = np.random.choice(Items, p=probabilities)
    drop['text'] = "You've recieved a drop: " + winner

    if winner == Items[0]:
        Loot_IMG = PhotoImage(file=Images[0])
        reward_img = Label(GUI, image = Loot_IMG, background = bg_color)
        reward_img.Loot_IMG = Loot_IMG #
        reward_img.grid(row = 3, column=1, sticky = N)
    elif winner == Items[1]:
        Loot_IMG = PhotoImage(file=Images[1])
        reward_img = Label(GUI, image = Loot_IMG, background = bg_color)
        reward_img.Loot_IMG = Loot_IMG #
        reward_img.grid(row = 3, column=1, sticky = N)
    elif winner == Items[2]:
        Loot_IMG = PhotoImage(file=Images[2])
        reward_img = Label(GUI, image = Loot_IMG, background = bg_color)
        reward_img.Loot_IMG = Loot_IMG #
        reward_img.grid(row = 3, column=1, sticky = N)
   # AND SO ON.....


#print("You've recieved a drop:", winner)

else:
    luck['text'] = "You are unlucky"

    #REMOVING IMAGE DOES NOT WORK
    Loot_IMG = PhotoImage(file="")
    reward_img = Label(GUI, image = Loot_IMG, background = bg_color)
    reward_img.Loot_IMG = Loot_IMG #
    reward_img.grid(row = 3, column=1, sticky = N)

此外，我还将提供我在函数中进一步构建的两个列表：

    Images = ["loot/Dexterous_prayer_scroll.png", "loot/Arcane_prayer_scroll.png",
      "loot/Twisted_buckler.png", "loot/Dragon_hunter_crossbow.png",
      "loot/Dinh's_bulwark.png", "loot/Ancestral_hat.png", "loot/Ancestral_robe_top.png",
      "loot/Ancestral_robe_bottom.png", "loot/Dragon_claws.png", "loot/Elder_maul.png",
      "loot/Kodai_insignia.png", "loot/Twisted_bow.png"]


# indivdual drop rates
Items = ["Dexterous prayer scroll", "Arcane prayer scroll",
         "Twisted buckler", "Dragon hunter crossbow",
         "Dinh's bulwark", "Ancestral hat", "Ancestral robe top",
         "Ancestral robe bottom", "Dragon claws",
         "Elder maul", "Kodai insignia", "Twisted bow"]

您可以使用内置的zip()函数以及类似的方法来排除重复的代码：

task lockDependencies {
    dependsOn = ['dependencies','--update-locks *:*']
}

还要注意，tkinter if chance >= chance_of_drop: winner = np.random.choice(Items, p=probabilities) drop['text'] = "You've recieved a drop: " + winner for item, image in zip(Items, Images): if winner == item: Loot_IMG = PhotoImage(file=image) reward_img = Label(GUI, image=Loot_IMG, background=bg_color) reward_img.Loot_IMG = Loot_IMG # reward_img.grid(row=3, column=1, sticky=N) break else: try: reward_img.destroy() # Remove any existing Label. except NameError: pass # Doesn't exist, ignore.类仅支持PhotoImage，.gif或.pgm格式的图像。要加载.ppm图像，您将需要使用Python Imaging Library（PIL）子模块的ImageTk.PhotoImage类。

更新为备注：

Tk 8.6 added built-in support for the .png图像文件格式，因此您可能不需要使用PIL。

使用循环减少代码并使用tkinter删除图像
