Hi, I’m at the instructions section on the link below.
However, I got a few lines that I think are not correct by using the proposed solution, instead of my approach, please check my attached notebook, where I tried to demonstrate the issue, and let me know which regex pattern is the right choice.

To make the assessment easier, I attached the notebook in image format.

If you want to check only the word
email or emails and its other forms, then the second one is perfect. Because when you specify word boundary (
\b), then it looks for a word, and in the first case, due to no word boundary, it will select
hate mail and
voicemail type of line or word.
Got your point but, upon looking at what the regex should match, that does not fit the description. Down below, aren’t these the strings that should be replaced?
The whole point here is that students spend considerable time writing a solution like me. However, when you click on the submit button, the programmer figures out that its answer is wrong and the career track progress bar does not move. Tuns out that hate mail and voicemail aren´t anything like e-mail or its variations, and if those got replaced, you’d end up with a title with no meaning at all. I’m a rookie Python leaner, though I think that solution is not 100% correct.
I think the aim of exercise is to make you aware about how to substitute strings using
regex and understanding the writing of regular expressions. And if you want any correction or found any bug you can submit a ticket here.
