1. Python中的异常栈跟踪 Python,在2.x中,异常对象可以是任何对象,异常对象和异常栈是分开的.python中用于处理异常栈的模块是traceback模块,它提供了print_exception.format_exception等输出异常栈等常用的工具函数. def func(a, b): return a / b if __name__ == '__main__': import sys import traceback try: func(1, 0) except Except…

近来编写一个程序,该程序可以在设定时间内,获取指定文件夹更新的文件夹和文件列表,并根据获取到的更新列表,做一些操作.由于所写程序是放在服务器上运行,为了保证程序在运行的过程中,不时不时跳出些异常信息出来吓其他用户,就在程序中添加了异常处理.将网上的资料整理下,试着将sys.exce_info()和traceback搭配一起使用.效果还算不错,以下信息是我当前处理异常的方式,其中type是异常的类型,value是出现异常的原因,traceback则是通过traceback追中到的异常信息,能够定位…

刚开始学习python,按照网上步骤搭建好pydev+eclipse的开发环境,运行print("hello world")提示下面错误: Error in sitecustomize; set PYTHONVERBOSE for traceback: KeyError: 'sitecustomize' 按照网上的一些做法,在环境变量里面添加PYTHONVERBOSE,并设置值为1,这个错误确实是消失了,但是报了更多的错,从这些错误中也无法找到原因,网上也看不到更多的解决方案,于是怀疑…

traceback模块被用来跟踪异常返回信息 如下例所示: import traceback try: raise SyntaxError, "traceback test" except: traceback.print_exc() 将会在控制台输出类似结果: Traceback (most recent call last): File "H:PythonWorkSpaceTestsrcTracebackTest.py", line 3, in <modu…
