Python使用CMD模块更优雅的运行脚本

本文实例讲述了Python使用CMD模块更优雅的运行脚本的方法。分享给大家供大家参考。具体分析如下：

平时由于经常给测试人员调试一些东西，虽然写了一些脚本，感觉还是不方便。

python的cmd模块提供的更优雅的方式，很喜欢。

刚写了一些平时常用的测试代码：

        try:
          res = func(*args, **kwargs)
          return res
        except:
          print "there is a wrong in %s, please input 'help %s' to get help" % (func.__name__, func.__name__[3:])
          return None
      return _func

这里权当cmd模块的简单学习了。

希望本文所述对大家的Python程序设计有所帮助。
