Close the tag, please!

In the meantime, you are working on one of your other projects. The company is going to develop a new product. It will help developers automatically check the code they are writing. You need to write a short script for checking that every HTML tag that is open has its proper closure.

You have an example of a string containing HTML tags:

<title>The Data Science Company</title>

You learn that an opening HTML tag is always at the beginning of the string. It appears inside <>. A closing tag also appears inside <>, but it is preceded by /.

You also remember that capturing groups can be referenced using numbers, e.g \4.

The list html_tags, containing three strings with HTML tags, and there module are loaded in your session. You can use print() to view the data in the IPython Shell.

  • Complete the regex in order to match closed HTML tags. Find if there is a match in each string of the list html_tags. Assign the result to match_tag.
  • If a match is found, print the first group captured and saved in match_tag.
  • If no match is found, complete the regex to match only the text inside the HTML tag. Assign it to notmatch_tag.
  • Print the first group captured by the regex and save it in notmatch_tag.
