BaseException除了包含所有的Exception外还包含了SystemExit,KeyboardInterrupt和GeneratorExit三个异常。 由此看来你的程序在捕获所有异常时更应该使用Exception而不是BaseException,因为另外三个异常属于更高级别的异常,合理的做法应该是交给Python的解释器处理。 except Exception as e和 except Exception, e: 代码示例如下: ...

使用traceback模块可以获取到最全的信息,和运行中出错的信息一致。 使用traceback.print_exc()可以将打印信息输出到控制台。 使用traceback.format_exc()获取异常信息的字符串,输出到指定位置。 import traceback try: 1/0 except Exception as e: # 直接将异常信息输出到控制台 ...
The error is FileNotFoundError (the exception name), which means that the file doesn't exist or perhaps the directory to it doesn't exist.That's a lot of information. It can be hard to understand why line 1 is meaningful or what Errno 2 means....
Format the exception part of a traceback using an exception value such as given by sys.last_value. The return value is a list of strings, each ending in a newline. Normally, the list contains a single string; however, for SyntaxError exceptions, it contains several lines that (when printe...
