Python 对象不可调用-线程

我试图构建一个窗口来控制我的程序，但当我执行它时：

Exception in thread Thread-1:
Traceback (most recent call last):
  File "D:\python3.8\lib\threading.py", line 932, in _bootstrap_inner
    self.run()
  File "D:\python3.8\lib\threading.py", line 870, in run
    self._target(*self._args, **self._kwargs)
TypeError: 'MainWindow' object is not callable

我不确定是语法错误还是其他原因

代码：

IDE:VS Code

您应该有一个init函数，您当前没有调用对象构造函数，因此您没有实际的对象。尝试添加init函数

class MainWindow:
    def __init__(self):
        self.start()
    def quit(self)->'mine':
        windows.destroy()
        exit()
    def start(self):
        self.frame = tk.Frame(windows)
        self.frame.pack(side=tk.BOTTOM)
        self.button = tk.Button(self.frame, text='quit', fg='red', command=quit)
        self.button.pack(side=tk.RIGHT)
        windows.mainloop()
t = threading.Thread(target = MainWindow())
t.start()

不能在线程中调用类。可以在线程中调用类的函数。首先创建类的对象，然后调用start函数。t=threading.Thread（target=obj.start（））

class MainWindow:
    def __init__(self):
        self.start()
    def quit(self)->'mine':
        windows.destroy()
        exit()
    def start(self):
        self.frame = tk.Frame(windows)
        self.frame.pack(side=tk.BOTTOM)
        self.button = tk.Button(self.frame, text='quit', fg='red', command=quit)
        self.button.pack(side=tk.RIGHT)
        windows.mainloop()
t = threading.Thread(target = MainWindow())
t.start()
