Python 搜索并打印值

Question

以下是文件输出。

vNIC Template:
Name: vNIC-120-A
Type: Updating Template
Fabric ID: A B

Ethernet Interface:
    Name: 2-native
    Dynamic MAC Addr: Derived
    Default Network: Yes
    State: progress

    Name: nfs
    Dynamic MAC Addr: Derived
    Default Network: No

    Name: vmotion
    Dynamic MAC Addr: Derived
    Default Network: No 

如何验证名称:2-native name 2-native 是否存在。

我可以使用下面的代码，无论它是否存在:

Counting the "string" occurrence in a file
def count_string_occurrence():
   string = "2-native"
   f = open("search.txt")
   contents = f.read()
   f.close()
   print "Number of '" + string + "' in file", contents.count("2-native")

就我而言，我搜索并找到了 2-Native 关键字。我想打印 2-native 的状态值和动态 Mac 地址值。下面是引用

    Name: 2-native
    Dynamic MAC Addr: Derived
    Default Network: Yes
    State: progress

就像我搜索“vNIC 模板”一样我想打印类型值和 Fabric 值。

Answer 1

我想你可以使用类似的东西:

import re
keyword = re.escape("2-native")
result = re.findall(r"Name: {}.*?Addr: ([\w]+).*?State: (.*?)$".format(keyword), contents, re.IGNORECASE | re.DOTALL | re.MULTILINE)
if result:
    mac_addr = result[0][0]
    state = result[0][1]
    print(mac_addr, state)
    # Derived progress
