title: is re.split("\W") = re.split("\w")?
body: <p>As the title says, is <code>re.split("\W")</code> the same as <code>re.split("\w")</code> because the results I get are the same whichever I use. The same goes if it has <code>+</code> or not. Is this right? Or it works in some cases, and if yes why? Thank you in advance.</p>
