I want to save the name of the error and the traceback details into a variable. Here's is my attempt.
import sys
try:
try:
print x
except Exception, ex:
raise NameError
except Exception, er:
print "0", sys.exc_info()[0]
print "1", sys.exc_info()[1]
print "2", sys.exc_info()[2]
Output:
0 <type 'exceptions.NameError'>
1
2 <traceback object at 0xbd5fc8>
Desired Output:
0 NameError
1
2 Traceback (most recent call last):
File "exception.py", line 6, in <module>
raise NameError
P.S. I know this can be done easily using the traceback module, but I want to know usage of sys.exc_info()[2] object here.
This is how I do it:
>>> import traceback
>>> try:
... int('k')
... except:
... var = traceback.format_exc()
...
>>> print var
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
ValueError: invalid literal for int() with base 10: 'k'
You should however take a look at the traceback documentation, as you might find there more suitable methods, depending to how you want to process your variable afterwards...
