Question

（如果赶时间，请跳至哈希标签）该程序仅在图像显示结束时才有效。我想将它用作另一个循环程序中的函数，但它不起作用。它将显示宠物小精灵的统计数据（p.whatever），但图像不会显示。该图像将显示在IDLE Python 3.4中，但不会显示在终端上。几个月来我一直坚持这个。

这是有效的程序（在IDLE Python 3.4中，而不是终端）：

import pykemon
print('What are you looking for?')
askedpokemon = input()


pokemonInDatabase = False
while pokemonInDatabase == False:
    pokemonInDatabase = True
    try:
        if ('1' in askedpokemon) or ('2' in askedpokemon) or ('3' in askedpokemon) or ('4' in askedpokemon) or ('5' in askedpokemon) or ('6' in askedpokemon) or ('7' in askedpokemon) or ('8' in askedpokemon) or ('9' in askedpokemon):
            p = (pykemon.get(pokemon_id = askedpokemon))

        else:
            askedpokemon = askedpokemon.lower()
            p = (pykemon.get(pokemon = askedpokemon))
            #Turns askedpokemon into number
            askedpokemon = p.resource_uri
            askedpokemon = askedpokemon.replace('/api/v1/pokemon/',' ')
            askedpokemon = askedpokemon.replace('/',' ')
            askedpokemon = askedpokemon.strip()


    except pykemon.exceptions.ResourceNotFoundError:
        print(askedpokemon + " is not a valid Pokemon name or id number.")
        print('Try another')
        askedpokemon = input()
        pokemonInDatabase = False



print (p)

pTypes = (p.types)
for key, value in pTypes.items() :
    pTypes = str(key)
    print ('   Type: ' + pTypes)
print ('     HP: ' + str(p.hp))
print (' Attack: ' + str(p.attack))
print ('Defense: ' + str(p.defense))
print (' Sp Atk: ' + str(p.sp_atk))
print (' Sp Def: ' + str(p.sp_def))
print ('  Speed: ' + str(p.speed))
print ('Exp Yield: ' + str(p.exp))

这是一个说明问题的mcve。调用文件tem.py。

import tkinter as tk
root = tk.Tk()
image = tk.PhotoImage(file='python.png')
label = tk.Label(image=image)
label.pack()

当您在终端中运行时，它会运行，但根窗口会在label.pack()之后关闭，然后才能看到它。将root.mainloop()放在代码的末尾，或者使用python -i tem.py运行（实际上是IDLE）。 -i表示在程序结束后从批处理切换到交互模式而不是关闭。 IDLE执行此操作，因此可以在关闭之前与实时程序进行交互。

图像不会循环显示，为什么不呢？
