traceback模块的作用

traceback模块被用来跟踪异常返回信息. 如下例所示:

1 2 3 4 5

import traceback try:     raise SyntaxError, "traceback test" except:     traceback.print_exc()

将会在控制台输出类似结果:

1 2 3 4

Traceback (most recent call last):   File "H:PythonWorkSpaceTestsrcTracebackTest.py", line 3, in <module>     raise SyntaxError, "traceback test" SyntaxError: traceback test
