How can you programmatically inspect the stack trace of an exception in Python?

Question

When an exception occurs in Python, can you inspect the stack? Can you determine its depth? I\'ve looked at the traceback module, but I can\'t figure out how to use it.

traceback is enough - and I suppose that documentation describes it rather well. Simplified example:

import sys
import traceback

try:
    eval('a')
except NameError:
    traceback.print_exc(file=sys.stdout)
