在python中打印空白异常

Question

我想弄清楚如果我不知道什么是异常，我将如何打印异常。我该怎么做？

try:
    some_command
except:
    print *full_exception_trace*

Answer 1

Like the tutorial says.

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

您可能会发现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会告诉你异常的原因

Answer 3

traceback模块的print_exc()功能似乎就是您想要的。 Docs
