Question

我正在尝试运行一个.py文件，该文件将输出一个.txt文件，其中包含从0.0.0.0到255.255.255.255的所有IP地址，但是在Sublime Text Console中抛出错误。这是我的.py文件：

def ipRange(start_ip, end_ip):
   start = list(map(int, start_ip.split(".")))
   end = list(map(int, end_ip.split(".")))
   temp = start
   ip_range = []

   ip_range.append(start_ip)
   while temp != end:
      start[3] += 1
      for i in (3, 2, 1):
         if temp[i] == 256:
            temp[i] = 0
            temp[i-1] += 1
      ip_range.append(".".join(map(str, temp)))    

   return ip_range

output = []   
# sample usage 
ip_range = ipRange("0.0.0.0", "255.255.255.255")
for ip in ip_range:
    output.append(ip)
fo = open("output.txt", "rw+")
line = fo.writelines(output)
fo.close()

这是我的控制台输出：

tput: No value for $TERM and no -T specified

我已经通过一些日志记录打印进行了修改，以通过以下方式调试代码流：-

   def ipRange(start_ip, end_ip):
       start = list(map(int, start_ip.split(".")))
       end = list(map(int, end_ip.split(".")))
       print('start', start)
       print('end', end)
       temp = start
       ip_range = []

       ip_range.append(start_ip)
       print('IP ADDRESS IS', ip_range)
       while temp != end:
          print('while ')
          start[3] += 1
          for i in (3, 2, 1):
             if temp[i] == 256:
                temp[i] = 0
                temp[i-1] += 1
      ip_range.append(".".join(map(str, temp)))    
      print('IP ADDRESS IS', ip_range)
      return ip_range


print("Executing the python script")
output = []   
# sample usage 
ip_range = ipRange("0.0.0.0", "0.0.0.10")
for ip in ip_range:
    print(ip)
    output.append(ip)
fo = open("output.txt", "w+")
line = fo.writelines(output)
fo.close()

请找到以下输出（我只打印10个ip地址）：-

[nikhilesh@pgadmin ~]$ python 2.py

('end', [0, 0, 0, 10])

我正在使用python 2.7.5版本
