#write:JACK

        ref = a.RemoveFtp()
        print 'Remove file ok!'
    else:
        a.ftps.quit()
        print 'Bingo!'
        break


#login(user='anonymous',passwd='', acct='') 登录到FTP服务器,所有的参数都是可选的
#pwd()                                     得到当前工作目录
#cwd(path)                                 把当前工作目录设置为path
#dir([path[,...[,cb]])       显示path目录里的内容,可选的参数cb 是一个回调函数,它会被传给retrlines()方法
#nlst([path[,...])           与dir()类似,但返回一个文件名的列表,而不是显示这些文件名
#retrlines(cmd [, cb])       给定FTP 命令(如“RETR filename”),用于下载文本文件。可选的回调函数cb 用于处理文件的每一行
#retrbinary(cmd, cb[,bs=8192[, ra]])        与retrlines()类似,只是这个指令处理二进制文件。回调函数cb 用于处理每一块(块大小默认为8K)下载的数据。
#storlines(cmd, f)           给定FTP 命令(如“STOR filename”),以上传文本文件。要给定一个文件对象f
#storbinary(cmd, f[,bs=8192])               与storlines()类似,只是这个指令处理二进制文件。要给定一个文件对象f,上传块大小bs 默认为8Kbs=8192])
#rename(old, new)            把远程文件old 改名为new
#delete(path)                删除位于path 的远程文件
#mkd(directory)              创建远程目录
#每个需要输入的地方,需要进行排查检错。仅仅这个功能太小了。不过根据实际情况更改,放在bt里边当个小工具即可
#有点烂,没有做任何try
