该文件以上述方式包含 100 个条目。我想找到“port-wwn（供应商）：20:32:00:02:ac:02:74:24”并读出“连接的接口”和“交换机名称”。所以在我的代码中我问用户输入 wwn 编号“xx:xx:...:xx”，然后我搜索该条目并找到行的索引并将 + 13 和 + 14 添加到索引并打印该索引的第 13 和第 14 行。

下面的代码有效，它给了我对应于 wwn "xx:xx:...:xx" 的行索引

with open("zones_list.txt", 'r') as f:
    #lines = f.readlines()
    for (i, line) in enumerate(f):
        if wwn in line:
            print("index is : " + str(i))
            #j = i + 13
            #k = i + 14
            #print(lines[j])
            #print(lines[k])
            break
f.close()

但是当我想在与我想要的阶段/字符串相对应的索引之后打印第 13 行和第 14 行时，它没有发生任何帮助吗？

with open("zones_list.txt", 'r') as f:
   lines = f.readlines()
    for (i, line) in enumerate(f):
        if wwn in line:
            print("index is : " + str(i))
            j = i + 13
            k = i + 14            
            print(lines[j])
            print(lines[k])
            break
f.close()

但是代码不起作用..还有其他方法可以编写代码..？谢谢！

解决方案

这应该有效：

wwn = input()

with open("zones_list.txt", 'r') as f:
   lines = f.readlines()
   for (i, line) in enumerate(lines):
        if wwn in line:
            print("index is : " + str(i))
            j = i + 13
            k = i + 14
            print(lines[j])
            print(lines[k])
            break

输入：

20:32:00:02:ac:02:74:24

输出：

index is : 3

connected interface         :fc1/3

switch name (IP address)    :c3-sn6610c-02 (15.112.42.197)
