TypeError: can't use a string pattern on a bytes-like object in re.findall()

I am trying to learn how to automatically fetch urls from a page. In the following code I am trying to get the title of the webpage:

    import urllib.request
    import re

    url = "http://www.google.com"
    regex = '<title>(,+?)</title>'
    pattern  = re.compile(regex)

    with urllib.request.urlopen(url) as response:
       html = response.read()

    title = re.findall(pattern, html)
    print(title)

And I get this unexpected error:

    Traceback (most recent call last):
      File "path\to\file\Crawler.py", line 11, in <module>
        title = re.findall(pattern, html)
      File "C:\Python33\lib\re.py", line 201, in findall
        return _compile(pattern, flags).findall(string)
    TypeError: can't use a string pattern on a bytes-like object

What am I doing wrong?

You want to convert html (a byte-like object) into a string using .decode, e.g. html = response.read().decode('utf-8').
