在Python中打印空白異常

Question

我想弄清楚如果我不知道如何排除異常，我將如何打印異常。我將如何做以下幾點？

try: 
    some_command 
except: 
    print *full_exception_trace* 

Answer 1

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會給你異常

Answer 2

Like the tutorial says.

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

您可能會發現traceback有用。

Answer 3

的原因的traceback模塊的print_exc()功能似乎是你想要的。 Docs
