捕获并打印完整的 Python 异常回溯，无需停止/退出程序

我想捕获并记录异常而不退出，例如，

try:
    do_stuff()
except Exception as err:
    print(Exception, err)
    # I want to print the entire traceback here,
    # not just the exception name and details

我想打印与引发异常时打印的输出完全相同的输出，而没有 try/ except 拦截异常，我这样做not希望它退出我的程序。

traceback.format_exc() http://docs.python.org/3/library/traceback.html#traceback.format_exc or sys.exc_info() http://docs.python.org/3/library/sys.html#sys.exc_info如果您想要的话，将产生更多信息。

import traceback
import sys

try:
    do_stuff()
except Exception:
    print(traceback.format_exc())
    # or
    print(sys.exc_info()[2])
