python写了一个子网掩码计算器

　　脑子笨，口算子网掩码有点慢，于是用python3 写了个子网掩码计算器，可以算IPV4和IPV6，支持192.168.1.1/24和192.168.1.1/255.255.255.0两种掩码方式。
　　脚本内容如下：from IPy import IP import tkinter   def ipmask(strs=＂＂):     try:         ip = IP(strs, make_net=True)         info = {}         info[＂IP/MASK＂] = str(ip)         info[＂MASK＂] = str(IP(ip).strNormal(2).split(＂/＂)[1])         info[＂LENGTH＂] = ip.len()         info[＂START＂] = str(ip[0])         info[＂END＂] = str(ip[-1])         ret = info     except:         ip = ＂＂         ret = ＂格式有误＂     return ret, ip   class MY_GUI():     def __init__(self, init_window_name):         self.init_window_name = init_window_name      def set_init_window(self):         self.init_window_name.title(＂IP子网掩码计算器＂)         self.init_window_name.geometry(＂500x610+500+100＂)         self.init_window_name.attributes(＂-alpha＂, 0.95)         self.ip_label = tkinter.Label(self.init_window_name, text=＂IP/MASK＂)         self.ip_label.pack(fill=tkinter.X, side=tkinter.TOP)         self.ip_text = tkinter.Entry(self.init_window_name)         self.ip_text.pack(fill=tkinter.X, side=tkinter.TOP, )         self.button = tkinter.Button(self.init_window_name, text=＂计算＂, width=13, command=self.trans)         self.button.pack(fill=tkinter.Y, side=tkinter.TOP)         self.result_data_Text = tkinter.Text(self.init_window_name)         self.scroll = tkinter.Scrollbar()         self.scroll.pack(side=tkinter.RIGHT, fill=tkinter.Y)         self.scroll.config(command=self.result_data_Text.yview())         self.result_data_Text.config(yscrollcommand=self.scroll.set)         self.result_data_Text.pack(fill=tkinter.Y, side=tkinter.TOP, expand=＂yes＂)      # 功能函数     def trans(self):         self.result_data_Text.delete(1.0, tkinter.END)         strs = self.ip_text.get()         info, ip = ipmask(strs)         if ＂MASK＂ in info:             self.result_data_Text.insert(tkinter.END,＂ ＂)             for i in info:                 self.result_data_Text.insert(tkinter.END, ＂{:<10}{} ＂.format(i, info[i]))             self.result_data_Text.insert(tkinter.END, ＂ {}  ＂.format(＂=＂ * 50))         else:             self.result_data_Text.insert(tkinter.END, info)          if ip:             if ip.len() > 65536:                 self.result_data_Text.insert(tkinter.END, ＂列表过大 ＂)             else:                 for i in ip:                     self.result_data_Text.insert(tkinter.END, str(i) + ＂ ＂)   def gui_start():     init_window = tkinter.Tk()     ZMJ_PORTAL = MY_GUI(init_window)     ZMJ_PORTAL.set_init_window()     init_window.mainloop()   gui_start()
