TypeError: can't use a string pattern on a bytes-like object
This error occurs when you try to use a string pattern to find matches in a bytes-like object, such as the response from a URL. To resolve this issue, you can convert the bytes-like object to a string before using it in a regular expression search.
In the context of your code, you are trying to use the re.findall() function to find the title of a web page. However, the html variable is a bytes-like object, and the pattern variable is a string. To fix this, you can decode the html variable using the decode() method, passing in the appropriate encoding (such as 'utf-8'), as shown below:
with urllib.request.urlopen(url) as response: html = response.read().decode('utf-8')
After this change, the code should work as expected and return the title of the web page.
