Python - 如何搜索字典键以查看它是否包含某个字符串

Question

我试图尽我所能地说出我的问题，因为我不确定这是不是我正在寻找的，对不起提前抱歉。

我正在使用feedparser解析RSS提要。

根据文档，我能够将我的结果解析为某个漏洞+ RSS帖子标题的链接。

这是我的代码：

import feedparser

# product variables
ie = ['Internet Explorer', 'IE', 'Explorer', 'Internet_Explorer']
nix = ['Linux', 'SUSE', 'Red Hat', 'RHEL', 'Ubuntu', 'Debian_Linux']
win = ['Windows_']

# NVD RSS feed variable
d = feedparser.parse('https://nvd.nist.gov/feeds/xml/cve/misc/nvd-rss-  analyzed.xml')
print("================================")
print(d['feed']['title'])
print("================================")

for entry in d.entries:
    print(entry.title, entry.link)

这将返回如下所示的结果：

CVE-2018-8132 (windows_10, windows_server_2016) https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2018-8132

我也试过解析原始数据，这是：

for entry in d.entries:
    print(entry)

现在这告诉我，title是字典中的关键（我认为），值为CVE-2018-8132 (windows_10, windows_server_2016)

我想做的是一个if语句，如下所示：如果titlevalue包含一个单词（从顶部列表中）然后做一些事情

我在feedparser的文档中找不到如何做到这一点。我真的很感激任何帮助。

编辑（2018-06-15）：

我想到了。

这是我的代码，无论是谁在将来寻找它：

# library imports
import feedparser
import re
import smtplib
import datetime
import time

# NVD RSS feed variable
d = feedparser.parse('https://nvd.nist.gov/feeds/xml/cve/misc/nvd-rss-  analyzed.xml')
print("\n+++++++++++++++++++++++++++++++++++++++")
print(d['feed']['title'], 'Scanner')
print("+++++++++++++++++++++++++++++++++++++++\n")


# function for iterating through the entries and printing out how many vulns there are
def product_scan(product_name):

    # vulnerability links list
    vuln_list = []

    # counter for how many vulns per product
    count = 0
    for entry in d.entries:
        if product_name in entry.title:
            count += 1
            # here we append the hyperlinks of the CVEs to a pre-defined list so we can manipulate it later
            vuln_list.append(entry.link)


    # making it look nice
    if count == 1:
 print('===============================================================\nThere is', count, product_name,
          'related vulnerability:')
    elif count == 0:
        print('')
    else:
      print('===============================================================\nThere are', count, product_name,
          'related vulnerabilities:')

    # this for loop is for enumerating the links for each product CVE code
    for x in vuln_list:
    print(x)


# calling the function and searching for vulns based on keyword(s)
product_list = ['mysql', 'windows', 'linux', 'explorer', 'php', 'webex', 'firefox', 'norton', 'mcafee', 'symantec']
for product in product_list:
    product_scan(product)
