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
想要捕获所有的异常，可以直接捕获 Exception 即可：
try:
...
except Exception as e:
...
log('Reason:', e) # important!
这个将会捕获除了 SystemExit 、 KeyboardInterrupt 和 GeneratorExit 之外的所有异常。 如果你还想捕获这三个异常，将 Exception 改成 baseException 即可。
以上这篇对Python中内置异常层次结构详解就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持考高分网。
