I want to get exception information in Python3
for example ... in foo.py
import sys
try:
{}.encode('utf8')
except:
err = sys.exc_info()[0]
print("itself\t", err)
print(".args\t", err.args)
print("dir\t", dir(err.args))
print("type\t", type(err.args))
print("vars\t", vars(err))
print("--------k,v in vars---------")
for k,v in vars(err).items():
print(k)
print(v)
and stdout ...
itself <class 'AttributeError'>
.args <attribute 'args' of 'BaseException' objects>
dir ['__class__', '__delattr__', '__delete__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__get__', '__getattribute__', '__gt__', '__hash__', '__init__', '__le__', '__lt__', '__name__', '__ne__', '__new__', '__objclass__', '__qualname__', '__reduce__', '__reduce_ex__', '__repr__', '__set__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']
type <class 'getset_descriptor'>
vars {'__init__': <slot wrapper '__init__' of 'AttributeError' objects>, '__doc__': 'Attribute not found.', '__new__': <built-in method __new__ of type object at 0x821c3a0>}
--------k,v in vars---------
__init__
<slot wrapper '__init__' of 'AttributeError' objects>
__doc__
Attribute not found.
__new__
<built-in method __new__ of type object at 0x821c3a0>
I want to get more information about this built-in Exception class from the "err" instance,
such as
- FILE: foo.py
- LINE: 4
- MESSAGE: object 'dict' does not have attribute 'encode'
just like stdout of this code
{}.encode('utf8')
this
Traceback (most recent call last):
File "foo.py", line 2, in <module>
{}.encode('utf8')
AttributeError: 'dict' object has no attribute 'encode'
