昨晚今晚写了两晚，总算把Py Port Scanner 写完了，姑且称之为0.1版本，算是一个Python多线程端口扫描工具。

水平有限，实话中间有一些困惑和不解的地方，代码可能也写的比较乱。有些问题并未找到很好的解决方法，还望大家谅解。速度大家自己试验，我感觉还行。

送上效果图两份，分别是扫单IP和扫IP段：

        example：port 21,23,25
        example: port 1000..2000
        example: port 80,443,1000..1500
    scan [IP] 扫描某一IP地址
        example: scan 192.168.1.5
    search [IP begin]-[IP end] 扫描某一IP段
        example: search 192.168.1.1-192.168.1.100
