我收到此错误：
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python27\lib\lib-tk\Tkinter.py", line 1470, in __call__
return self.func(*args)
TypeError: <lambda>() takes exactly 1 argument (0 given)
当我打电话给这个班级时
class settingsWindow:
def __init__(self, master, settings):
self.master = master
self.titleLb = tk.Label(self.master, text='MesterMind', font=('Calibri', 22))
self.titleLb.grid(row=0, column=0, sticky='W', columnspan=2)
self.subTitleLb = tk.Label(self.master, text="Settings", font=('Calibri', 18))
self.subTitleLb.grid(row=1, column=0, sticky='W', columnspan=2)
使用它来创建类的实例
def settings(self):
self.settingsWindow = tk.Toplevel(self.master)
self.app = settingsWindow(self.settingsWindow, self.settings)
我不知道是什么导致了错误，也没有在代码中看到任何明显的错误。我正在使用 python 2.7
任何帮助表示赞赏，谢谢。
编辑：注意，tk 是 Tkinter 模块
这里编辑的是整个 python 模块，（MasterMind.py）。我认为所有相关部分都在上面。
