Code explanation

  • import re: imports the re module which provides regular expression matching operations.
  • url = 'https://www.example.com/path/to/page': assigns the URL to a variable.
  • re.search(r'https?://(www\.)?\w+\.\w+/\S+', url): searches for a match of the regular expression pattern in the URL. The pattern consists of the following parts:
    • https?://: matches http or https at the beginning of the URL.
    • (www\.)?: matches www. at the beginning of the URL, if present.
    • \w+\.\w+: matches the domain name.
    • /\S+: matches the path of the URL.
  • if match:: checks if a match was found.
  • print(match.group()): prints the matched URL.
