所以我一直试图用tkinter构建一个简单的文本编辑器，但不幸的是，当我在Python中使用open((函数打开特定文件时，会出现一个错误，在第83行显示'TypeError:'PhotoImage'对象不可调用'。这和PhotoImage有什么关系？这可能与Image.open((有关吗？这是代码：

问题是将内置函数open作为变量分配给PhotoImage。现在，当您调用open时，它会获取open变量的值，因为它被分配了一个值。这将导致错误。这就是为什么永远不应该将内置函数用作变量的原因。您可以使用open_img或任何不是关键字、内置函数或您定义的函数的东西。
open = Photos(nm + 'open.png', 10, 10)，这是一个错误
open_img = Photos(nm + 'open.png', 10, 10)这是可行的。
然后将菜单更新为fileMenu.add_command(label='Open...', command=openfiles, image=open_img, compound='left')
