无法处理的类型：int（）<Entry（）

Question

我一直在我的程序中遇到这个错误，我不知道如何解决它，因为我是python 3中的初学者。每当我尝试更改时就会发生错误菜单内的网格大小。然后我去运行宝藏网格，我得到这个错误，并没有线索如何解决。任何和所有的帮助表示赞赏！

错误：

只处理特定问题，你与tk.Entry()即比较int()。 len(treasureChests) < treasure_amount len返回一个int和treasure_amount是输入框。要只解决这个问题，while循环改成这样：

while len(treasureChests) < int(treasure_amount.get()): 

使用.get()它检索输入框的值，并int()从默认str 转换有可能是更多的问题，后来就上来了。

请注意，尽量少用global声明。

编辑进一步检查后，我看到这是一个常见的名称错误，你有两个不同的对象设置为相同的变量。第一个是在顶部：

treasure_amount = 10 

另外一个是在你的settings_window：

global treasure_amount 
treasure_amount = tk.Entry(settings, width=50, fg="magenta") 

那么你或许应该改变他们的名字之一。
