How can I retrieve the page title of a webpage using Python?

Question

How can I retrieve the page title of a webpage (title html tag) using Python?

Answer 1

Using HTMLParser:

from urllib.request import urlopen
from html.parser import HTMLParser


class TitleParser(HTMLParser):
    def __init__(self):
        HTMLParser.__init__(self)
        self.match = False
        self.title = ''

    def handle_starttag(self, tag, attributes):
        self.match = tag == 'title'

    def handle_data(self, data):
        if self.match:
            self.title = data
            self.match = False

url = "http://example.com/"
html_string = str(urlopen(url).read())

parser = TitleParser()
parser.feed(html_string)
print(parser.title)  # prints: Example Domain

No need to import other libraries. Request has this functionality in-built.

>> hearders = {'headers':'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:51.0) Gecko/20100101 Firefox/51.0'}
>>> n = requests.get('http://www.imdb.com/title/tt0108778/', headers=hearders)
>>> al = n.text
>>> al[al.find('<title>') + 7 : al.find('</title>')]

This is probably overkill for such a simple task, but if you plan to do more than that, then it's saner to start from these tools (mechanize, BeautifulSoup) because they are much easier to use than the alternatives (urllib to get content and regexen or some other parser to parse html)

Links: BeautifulSoup mechanize

#!/usr/bin/env python
#coding:utf-8

from BeautifulSoup import BeautifulSoup
from mechanize import Browser

#This retrieves the webpage content
br = Browser()
res = br.open("https://www.google.com/")
data = res.get_data() 

#This parses the content
soup = BeautifulSoup(data)
title = soup.find('title')

#This outputs the content :)
print title.renderContents()

Answer 4

Use soup.select_one to target title tag

import requests
from bs4 import BeautifulSoup as bs

r = requests.get('url')
soup = bs(r.content, 'lxml')
print(soup.select_one('title').text)

Here is a fault tolerant HTMLParser implementation.
You can throw pretty much anything at get_title() without it breaking, If anything unexpected happens get_title() will return None.
When Parser() downloads the page it encodes it to ASCII regardless of the charset used in the page ignoring any errors. It would be trivial to change to_ascii() to convert the data into UTF-8 or any other encoding. Just add an encoding argument and rename the function to something like to_encoding().
By default HTMLParser() will break on broken html, it will even break on trivial things like mismatched tags. To prevent this behavior I replaced HTMLParser()'s error method with a function that will ignore the errors.

I'll always use lxml for such tasks. You could use beautifulsoup as well.

import lxml.html
t = lxml.html.parse(url)
print t.find(".//title").text

EDIT based on comment:

from urllib2 import urlopen
from lxml.html import parse

url = "https://www.google.com"
page = urlopen(url)
p = parse(page)
print p.find(".//title").text
