如下所示：

BaseException +-- SystemExit +-- KeyboardInterrupt +-- GeneratorExit +-- Exception  +-- StopIteration  +-- StandardError  | +-- BufferError  | +-- ArithmeticError  | | +-- FloatingPointError  | | +-- OverflowError  | | +-- ZeroDivisionError  | +-- AssertionError  | +-- AttributeError  | +-- EnvironmentError  | | +-- IOError  | | +-- OSError  | |   +-- WindowsError (Windows)  | |   +-- VMSError (VMS)  | +-- EOFError  | +-- ImportError  | +-- LookupError  | | +-- IndexError  | | +-- KeyError  | +-- MemoryError  | +-- NameError  | | +-- UnboundLocalError  | +-- ReferenceError  | +-- RuntimeError  | | +-- NotImplementedError  | +-- SyntaxError  | | +-- IndentationError  | |   +-- TabError  | +-- SystemError  | +-- TypeError  | +-- ValueError  |   +-- UnicodeError  |    +-- UnicodeDecodeError  |    +-- UnicodeEncodeError  |    +-- UnicodeTranslateError  +-- Warning   +-- DeprecationWarning   +-- PendingDeprecationWarning   +-- RuntimeWarning   +-- SyntaxWarning   +-- UserWarning   +-- FutureWarning  +-- ImportWarning  +-- UnicodeWarning  +-- BytesWarning

想要捕獲所有的異常，可以直接捕獲 Exception 即可：

try: ...except Exception as e: ... log('Reason:', e)  # Important!

這個將會捕獲除了 SystemExit 、 KeyboardInterrupt 和 GeneratorExit 之外的所有異常。 如果你還想捕獲這三個異常，將 Exception 改成 BaseException 即可。

以上這篇對Python中內置異常層次結構詳解就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持武林站長站。
