一段代码被try ... except Exception,e 后，有什么办法获得抛出异常的具体位置或者行号呢？！如果直接print e 只能看到
异常信息而不能看到详细的出错位置

traceback.print_exc() ?

的确不不错，有没有人测过，traceback 会不会占用很多资源？！

应该不占.异常信息里面其实都有,在sys模块中,traceback只不过是可以进行更细致的处理,比如自行加工等.

我用下面的代码测试了一下，似乎没有速度变化。（也不知道这样测试有没有意义）
# -*- coding: cp936 -*-
#import traceback
import time
def f1():
    str("1")
    f2()

def f2():
    str("2")
    f3()

def f3():
    str("3")

try:
    startTime = time.time()
    for i in xrange(10e6):
        str(i)
        f1()
    endTime = time.time()
    print "Time:", (endTime - startTime)
except Exception, e:
#    print traceback.format_exc()
    pass

结果：
Time: 27.9220001698 ,导入 traceback, 并在后面添加
Time: 28.0309998989 不导入traceback, 并注释print traceback.format_exc()

目的是想知道，在程序中使用了traceback是否会影响程序效率。

这纯粹只有调试时使用的招，
调试好了，自然要清除的哪？！
