每当我运行以下代码时，我都会收到此错误。我使用Python 3可能是我使用Python 2的代码。
Traceback (most recent call last):
File "Python Fun", line 238, in <module>
platform1 = PlatformSprite(g, tk.PhotoImage(file="platform1.gif"), 0, 480,100, 10)

我该怎么办？

答案 0 :(得分：0)
我认为问题是你有专门针对Game（）类的Tk（）对象。尝试将root = tk.Tk()放在python的最顶层，然后使用root /传递它来获取Tkinter工作的句柄。此外，您正在使用名为＆＃34; tk＆＃34;的变量。甚至在你将Tkinter作为tk导入之后。考虑为该变量使用不同的名称，否则可能会遇到一些问题。
