如果一个地址集包含一些特定的单词，我如何搜索

Question

我正在写一个程序，我必须检查地址集中的所有地址是否都包含特定的关键字：

例如A：

set group address "Private-MT" "ABCD45-48/70-71"

set group address "Private-MT" "ABCD45-48/70-71" add "ABCD47"

set group address "Private-MT" "ABCD45-48/70-71" add "ABCD48"

set group address "Private-MT" "ABCD45-48/70-71" add "ABCD70"

set group address "Private-MT" "ABCD45-48/70-71" add "ABCD71"

例如B：

set group address "Private-MT" "ABCD45-48/XYCD70-71"

set group address "Private-MT" "ABCD45-48/XYCD70-71" add "ABCD47"

set group address "Private-MT" "ABCD45-48/XYCD70-71" add "ABCD48"

set group address "Private-MT" "ABCD45-48/XYCD70-71" add "XYCD70"

set group address "Private-MT" "ABCD45-48/XYCD70-71" add "XYCD71"

在本例中，地址集的名称是“ABCD45-48/70-71”，因此在完全删除此地址集之前，我需要检查此地址集的所有成员的名称中必须包含ABCD。你知道吗

如果他们都有ABCD在那里的名称删除整个地址集

A的输出：

unset group address "Private-MT" "ABCD45-48/70-71"

否则删除特定行。你知道吗

B的输出：

unset group address "Private-MT" "ABCD45-48/XYCD70-71" add "ABCD47"

unset group address "Private-MT" "ABCD45-48/XYCD70-71" add "ABCD48"

Answer 1

你的问题不太清楚，但我会在标题里问你的问题。如果您有一个字符串，并且希望搜索子字符串，则只能使用

if substring in string:
     #do what you want to do

另一种方法是使用正则表达式，这里是文档re python

下次请分享你的脚本，帮助大家理解你的问题；）

编辑

filename = "test.text"
import re
def splitAddresses(data):
    addresses=[]
    l=[]
    pattern=re.compile("^[GROUP]+[0-9]+[:]$")
    for element in data:
        isAmatch=pattern.match(element)
        if isAmatch==None:
            l.append(element)
        else:
            addresses.append(l)
            l=[]
    addresses.append(l)
    return(addresses[1:])
def parseAddress():
    with open(filename) as f:
        data = f.readlines()
    addresses=splitAddresses(data)
    for element in addresses:
        prefix=element[0][32:36]
        length_data=len(element)
        for address in element[1:]:
            if address.count(prefix)!=2:
                element.remove(address)
        new_length = len(element)
        if new_length==length_data:
            print(element[0])
        else:
            print(element[1:])
parseAddress()

尝试使用此文件

GROUP1:
set group address "Private-MT" "ABCD45-48/70-71"
set group address "Private-MT" "ABCD45-48/70-71" add "ABCD47"
set group address "Private-MT" "ABCD45-48/70-71" add "ABCD48"
set group address "Private-MT" "ABCD45-48/70-71" add "ABCD70"
set group address "Private-MT" "ABCD45-48/70-71" add "ABCD71"
GROUP2:
set group address "Private-MT" "ABCD45-48/70-71"
set group address "Private-MT" "ABCD45-48/70-71" add "ABCD47"
set group address "Private-MT" "ABCD45-48/70-71" add "ABCD48"
set group address "Private-MT" "ABCD45-48/70-71" add "XYCD70"
set group address "Private-MT" "ABCD45-48/70-71" add "XYCD71"

输出为：

set group address "Private-MT" "ABCD45-48/70-71"

['set group address "Private-MT" "ABCD45-48/70-71" add "ABCD47"\n', 'set group address "Private-MT" "ABCD45-48/70-71" add "ABCD48"\n']

您可以编辑脚本并存储信息，因为我做了一个打印，向您展示了它的工作原理；）
