AttributeError: 'master' object has no attribute '_loadtk'

Question

我正在尝试为已经可用的 python 模块制作一个 GUI 作为一个项目。我是 Tkinter 的新手，所以我在这里和那里使用了 Bryan Oakley 的这个答案作为我工作的参考。此处的 GUI python 文件应该从用户那里获取数据并使用其他 python 模块 PdbHandler 和 CrdHandler 生成必须使用 Tkinter 显示的数据文件。下面附上的是显示错误属性错误 'Master' object has no attribute '_loadtk' 的项目的当前进度。

  File "C:\Users\Dark12Arrow\AppData\Local\Programs\Python\Python37-32\lib\tkinter\__init__.py", line 2022, in __init__
self._loadtk()
AttributeError: 'master' object has no attribute '_loadtk'

我尝试使用 root=tk.Tk() 并将 root 传递给 master 在此查询中出现了类似的问题 Python Tkinter error object has no attribute。但这显示了另一个错误。

 File "C:\Users\Dark12Arrow\AppData\Local\Programs\Python\Python37-32\lib\tkinter\__init__.py", line 2020, in __init__
self.tk = _tkinter.create(screenName, baseName, className, interactive, 
wantobjects, useTk, sync, use)
TypeError: create() argument 1 must be str or None, not Tk

由于代码仍然不完整，第二页只是一个空白页：

class PageTwo(tk.Frame):
    def __init__(self,parent,controller):
        tk.Frame.__init__(self,parent)

app= master()
app.mainloop()

Answer 1

第 8 行不应该是：

super().__init__(*args, **kwargs)

Answer 2

问题出在这三行：

class master(tk.Frame):
    def __init__(self, *args, **kwargs):
        tk.Tk.__init__(self, *args, **kwargs)

您继承自tk.Frame，但随后尝试调用tk.Tk的__init__方法上述代码段的第一行和第三行需要就[=18]达成一致=].
