我是python中OOPS的新手。我创建了以下输入文件。我编写了python代码来获取输入文件到本地类变量的详细信息。我需要帮助创建一种更好的方式来安排和访问输入文件。
DETAILS INPUT FABRIC -A FABRIC -A FABRIC -A FABRIC-A FABRIC -B FABRIC -B FABRIC -B FABRIC-B
ARRAY_SERIAL # T663xt AB12343
HOST_NAME aaaaa 10000090FA87EC7A 10000090FA87EC7B 10000090FA87EC7C 10000090FA87EC7C SEPERATION 10000091FA87EC7B 10000091FA87EC7C 10000091FA87EC7D 10000091FA87EC7D
HOST_NAME bbbbb 10000091FA87ED8A 10000091FA87FC8B 10000091FA87EC8C 10000091FA87EC8D SEPERATION 10000092FA87ED8E 10000092FA87FC8F 10000092FA87EC8G 10000092FA87EC8H
HOST_NAME ccccc 10000093FA87ED8D 10000093FA87FC8 10000093FA87EC8C 10000093FA87EC8C SEPERATION 10000093FA87ED8D 10000093FA87FC8D 10000093FA87EC8C 10000093FA87EC8C
CLUSTER YES
FAB_A_FA 1E:0 2F:0 3G:0
FAB_B_FA 16E:0 15F:0 14G:0
我在第一列中有我的值，在下一列中有我自己的值。
我创建了一个调用，其中包含第1列中所有元素的类变量，如数组，主机（字典），集群，fa_A（字典），fa_B（字典）。
我将它们存储在变量中，以便我可以访问它们以生成一些打印语句。
例如，切换命令功能将为主机生成切换命令
alicreate "aaaaa_hba1", "10000090FA87EC7A"
alicreate "aaaaa_hba2", "10000090FA87EC7B"
alicreate "aaaaa_hba3", "10000090FA87EC7C"
zonecreate "aaaaa_hba1_T663xt_1E_0", "aaaaa_hba1;T663xt_1E_0"
依此类推，我想知道最好的方法是什么。为输入文件中的所有主机创建类主机和实例化主机并生成等等是否会更好。
请在下面找到我的代码。

我假设在数以千计的数百万的记录中，记录的数量并不大。 如何解析并将规范化数据保存在内存中，如下所示。 在实施过程中，请致电相应的项目了解详情。
数据结构：
serials (list or set)
host (dictionary)
{
name: "aaaa"
Fabric-A: [] (list or set)
Fabric-B: [] (list or set)
}
cluster (bool)
fab_A = (dictionary)
fab_B = (dictionary)
