如何在不停止程序的情况下打印完整的回溯？

问题：

I'm writing a program that parses 10 websites, locates data files, saves the files, and then parses them to make data that can be readily used in the NumPy library. 我正在编写一个程序，该程序可以解析10个网站，找到数据文件，保存文件，然后解析它们以生成可以在NumPy库中轻松使用的数据。 There are tons of errors this file encounters through bad links, poorly formed XML, missing entries, and other things I've yet to categorize. 有过不良链接，不好的XML，缺项，其他的事情我还没有进行分类文件遭遇吨的错误。 I initially made this program to handle errors like this: 我最初制作该程序来处理以下错误：

try:
    do_stuff()
except:
    pass

But now I want to log errors: 但是现在我想记录错误：

try:
    do_stuff()
except Exception, err:
    print Exception, err

Note this is printing to a log file for later review. 请注意，这是打印到日志文件以供以后查看。 This usually prints very useless data. 这通常会打印非常无用的数据。 What I want is to print the exact same lines printed when the error triggers without the try-except intercepting the exception, but I don't want it to halt my program since it is nested in a series of for loops that I would like to see to completion. 我想要的是在错误触发时打印完全相同的行，而没有try-except拦截异常，但是我不希望它暂停我的程序，因为它嵌套在我想要的一系列for循环中看到完成。
