嵌套的循环+格式化多个列表

Question

这里是到目前为止的代码
关于变量注：
'ports' - 有可能是在“端口”列表
'nodes_u'这将包含任何数量的服务器的任意端口数目名称和IP地址对
'serv_name_u'可以是任何东西，但是是静态的，一旦定义
'port_qty'等于在“端口”

ports = ['443', '80'] 
nodes_u = ['SERVER1', '10.0.0.1', 'SERVER2', '10.0.0.2'] 
serv_name_u = "TESTING" 
port_qty = 2 

for i in range(0, len(ports)): 
    print("ltm pool "+serv_name_u+"_{0}_pool {{ \n members {{" 
      .format(ports[i])) 
    for i in range(0, len(nodes_u), 2): 
     print("  {0} {{ \n   address {1} \n  }}" 
       .format(nodes_u[i], nodes_u[i+1])) 

上市的端口数

这里是输出

ltm pool TESTING_443_pool { 
    members { 
     SERVER1 { 
      address 10.0.0.1 
     } 
     SERVER2 { 
      address 10.0.0.2 
     } 
ltm pool TESTING_80_pool { 
    members { 
     SERVER1 { 
      address 10.0.0.1 
     } 
     SERVER2 { 
      address 10.0.0.2 
     } 

我的问题还是什么，我试图找出是怎样才能得到仅在池部分中的服务器名称后显示的端口号的例子！所以输出就像这样

ltm pool TESTING_443_pool { 
    members { 
     SERVER1:443 { <<<Port Number Here! 
      address 10.0.0.1 
     } 
     SERVER2:443 { <<<Port Number Here! 
      address 10.0.0.2 
     } 
ltm pool TESTING_80_pool { 
    members { 
     SERVER1:80 { <<<Port Number Here! 
      address 10.0.0.1 
     } 
     SERVER2:80 { <<<Port Number Here! 
      address 10.0.0.2 
     } 

每次我尝试一些我刚刚结束了上市的两个端口或迭代跳过去的指数范围为“端口”名单。此外，如果有更好的方法来捕捉输入或生成输出，我全是耳朵！

删除嵌套for -loop，只是包括在所述外for -loop两个打印语句，与索引:{1}插入port数：

for i in range(0, len(ports)): 
    print("ltm pool "+serv_name_u+"_{0}_pool {{ \n members {{" 
      .format(ports[i])) 
    # for i in range(0, len(nodes_u), 2): 
    print("  {0}:{1} {{ \n   address {2} \n  }}" 
      .format(nodes_u[i], ports[i], nodes_u[i+1])) 

输出：

List of nodes: 
ltm node SERVER1 { 
    address 10.0.0.1 
    } 
ltm node SERVER2 { 
    address 10.0.0.2 
    } 
ltm pool TESTING_443_pool { 
    members { 
     SERVER1:443 { 
      address 10.0.0.1 
     } 
ltm pool TESTING_80_pool { 
    members { 
     10.0.0.1:80 { 
      address SERVER2 
     } 

尝试＃2： 使用不同的增量器名称（i和j）在嵌套for -loops两个名单区分可以得到需要的结果：

for i in range(0, len(ports)): 
    print("ltm pool "+serv_name_u+"_{0}_pool {{ \n members {{" 
      .format(ports[i])) 
    for j in range(0, len(nodes_u), 2): 
     print("  {0}:{1} {{ \n   address {2} \n  }}" 
       .format(nodes_u[j], ports[i], nodes_u[j+1])) 

输出：

ltm pool TESTING_443_pool { 
    members { 
     SERVER1:443 { 
      address 10.0.0.1 
     } 
     SERVER2:443 { 
      address 10.0.0.2 
     } 
ltm pool TESTING_80_pool { 
    members { 
     SERVER1:80 { 
      address 10.0.0.1 
     } 
     SERVER2:80 { 
      address 10.0.0.2 
     } 

作为一种更好的方法来捕捉输入或生成输出，可以考虑使用输入的数据结构不同，如dictionary，keys为name，port和values分别为values。
