跟踪异常情况以及是否已处理

Question

How would I keep track of exceptions so that I could find out whether or not they have been handled or not?

假设我有一些错误处理代码：

def errorWindow(self, error_):
    self.filewin = Toplevel(self.master)
    self.NothingLabel = Label(self.filewin,text=error_,justify=CENTER)
    self.NothingLabel.pack()
    self.nbutton = Button(self.filewin, text="OK", command=self.filewin.destroy)
    self.nbutton.pack(pady=5)

# When it is called it looks something like this:
    try:
       # Function that is being checked for exceptions
    except Exception as e:
        error_ = 'Failure the following error was encountered: \n {}'.format(e)
        self.errorWindow(error_)

我想做的是使用我构建的函数来处理我期望在用户端发生的错误。我想有一个函数，也创建了一个错误窗口时，用户发生的错误，我不期望。理想情况下，只有在发生异常时才会发生这种情况。那么，有没有一种方法来识别和跟踪特定的异常，以便我可以用一种不同于预期的方式来处理意外错误呢
