感谢Alex的指导，以下是代码：
def trimmedexceptions(type, value, tb, pylibdir=None, lev=None):
"""trim system packages from the exception printout"""
if pylibdir is None:
import traceback, distutils.sysconfig
pylibdir = distutils.sysconfig.get_python_lib(1,1)
nlev = trimmedexceptions(type, value, tb, pylibdir, 0)
traceback.print_exception(type, value, tb, nlev)
else:
fn = tb.tb_frame.f_code.co_filename
if tb.tb_next is None or fn.startswith(pylibdir):
return lev
else:
return trimmedexceptions(type, value, tb.tb_next, pylibdir, lev+1)
import sys
sys.excepthook=trimmedexceptions
# --- test code ---
def f1(): f2()
def f2(): f3()
def f3():
import xmlrpclib
proxy = xmlrpclib.ServerProxy('http://nosuchserver')
proxy.f()
f1()
产生以下堆栈跟踪：
