Question

它将打印前20个firefox历史记录并保存到html文件中，所有操作均在python3中完成。而且我必须在python2中做同样的事情。有什么办法可以修改此代码，也可以通过其他任何方法来修改python2。

GROUP BY

Answer 1

以下代码应该起作用

import os
import sqlite3
import operator
from collections import OrderedDict
import matplotlib.pyplot as plt
from urlparse import urlparse

def parse(url):
try:
parse_url = urlparse(url)
domain = parse_url.netloc
return domain
except IndexError:
print("URL format error")

def analyse(results):

plt.bar(range(len(results)), results.values(), align='edge')
plt.xticks(rotation=20)
plt.xticks(range(len(results)), results.keys())

plt.show()

data_path = os.path.expanduser('~')+"/.mozilla/firefox/7xov879d.default"
files = os.listdir(data_path)
history_db = os.path.join(data_path, 'places.sqlite')

c = sqlite3.connect(history_db)
cursor = c.cursor()
select_statement = "select moz_places.url, moz_places.visit_count from moz_places;"
cursor.execute(select_statement)

results = cursor.fetchall()
sites_count = {}

for url, count in results:
url = parse(url)

if url in sites_count:
sites_count[url] += 1
else:
sites_count[url] = 1

sites_count_sorted = OrderedDict(sorted(sites_count.items(), key=operator.itemgetter(1), reverse=True)[:10])

analyse(sites_count_sorted)

使用python2提取Firefox历史记录
