can't print the exception cause/context in Python3.0?

[BigHand]

Here is copy from my IDLE of python 3.0

b()

return tuple()[0]
a()
except:
exc_typ, exc_val, exc_tb = sys.exc_info()

File "<pyshell#14>", line 2, in <module>
File "<pyshell#6>", line 2, in a
File "<pyshell#9>", line 2, in b

but this doesn't output the cause/context like 2.6: or on the sample
of:
http://docs.python.org/3.0/library/...t=format_exception#traceback.format_exception

I want the exception printted like this:
File "<pyshell#14>", line 2, in <module> "a()"
File "<pyshell#6>", line 2, in a "b()"
File "<pyshell#9>", line 2, in b "return tuple()[0]"


how should I do?

Put your code in a true module stored in a file, so the source lines can
be retrieved.

hello,Gabriel,
I don't understand you.could you give me more details?
http://docs.python.org/3.0/library/...t=format_exception#traceback.format_exception
the up page is from python 3.0's doc. maybe from a older version of
Python,

even I excute these file in a py script file, it's can't retrieve the
source line either.

hello.Gabriel,
thanks very much!

My another issue is that, I have an embedded python3.0 in my MFC app,
use the PyRun_File to execute the Py script file, and call the python
function traceback.print_tb to print the traceback info,

but I can't get souce showed in the traceback.

solve it.
I need to "import traceback" first in the script file. or I can't get
the source retrieved later.
