Here's an example:

import shutil
from tempfile import NamedTemporaryFile

from datetime import datetime
from collections import defaultdict

def chrome_history(lr_session):

    users = set([proc['username'].split('\\')[-1]
                 for proc in running_processes if proc['path'].find('explorer.exe') != -1])

    chrome_history_urls = defaultdict(list)

    for user in users:
        with NamedTemporaryFile(delete=False) as tf:
            try:

                    "c:\\users\\%s\\appdata\\local\\google\\chrome\\user data\\default\\history" % user)
                shutil.copyfileobj(history_fp, tf.file)
                tf.close()
                db = sqlite3.connect(tf.name)
                db.row_factory = sqlite3.Row
                cur = db.cursor()
                cur.execute(
                    "SELECT url, title, datetime(last_visit_time / 1000000 + (strftime('%s', '1601-01-01')), 'unixepoch') as last_visit_time FROM urls ORDER BY last_visit_time DESC LIMIT 10")
                urls = [dict(u) for u in cur.fetchall()]
            except:
