使用cmd模块，让脚本更舒服些

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：

# -*- coding:utf-8 -*-

import os, sys
from datetime import datetime
import cmd
import warnings


from django.conf import settings


def not_exit(func):
    def _func(*args, **kwargs):
        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

class NBScript(cmd.Cmd):
    
    def __init__(self):
        cmd.Cmd.__init__(self)

        #配置django环境
        pathname = os.path.dirname(sys.argv[0])
        sys.path.append(os.path.abspath(pathname))
        sys.path.append(os.path.normpath(os.path.join(os.path.abspath(pathname), '../')))
        os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

权当cmd模块的简单学习了。
