python - 在python中打印空白异常

Question

我试图弄清楚如果我首先不知道异常是什么，我将如何打印异常。我将如何执行以下操作？

try:
    some_command
except:
    print *full_exception_trace*

Answer 1

就像教程说的那样。

try:
  something()
except SomeException as e:
  something_else(e)

你可能会觉得traceback有用。

Answer 2

def exception(self)
    try:
        Something.objects.all()
    except Exception, err:
        print err.message #(if you want)
        #raise err
        raise # The 'raise' statement with no arguments inside an error
              # handler tells Python to re-raise the exception with the 
              # original traceback intact

err.message 会给你异常的原因

Answer 3

该traceback模块的print_exc()功能似乎是您想要的。文档
