您如何找到定义自定义异常的位置以便您可以导入它。在我的代码中引发的错误的堆栈跟踪中，我得到了 NoSuchElementException。我想捕捉这个特定的异常，但我找不到从哪里导入它。有没有办法确定从堆栈跟踪中导入什么？

Traceback (most recent call last):

    welcome_field = driver.find_element_by_class_name(self.welcome_id)

捕获异常，Exception以便您可以访问异常对象：

try:
    call_your_function()
except Exception as e:
    print e.__module__

然后用Exception你找到的更具体的替换。
