按照上述方式，该文件有100个条目。我想找到"；端口wwn(供应商(：20:32:00:02:ac:02:74:24"；并读出"；连接接口"；以及"；交换机名称"；。。因此，在我的代码中，我要求用户输入wwn编号"；xx:xx:…：xx"；我搜索该条目，找到第行的索引，将+13和+14添加到索引中，并打印该索引中的第13行和第14行。

下面的代码给了我对应于wwn"的行索引；xx:xx:…：xx"；

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，当我想打印与我想要的相位/字符串相对应的索引之后的第13行和第14行时，这没有任何帮助？

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。。还有其他写代码的方法吗。。？非常感谢。

Answer 1

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)
