How do I check if a string contains no characters? : <p>I know this is a similar post to <a href="https://stackoverflow.com/questions/2405292/how-to-check-if-text-is-empty-spaces-tabs-newlines-in-python">How to check if text is &quot;empty&quot; (spaces, tabs, newlines) in Python?</a>
, however I'm still having troubles.</p>

<p>I don't understand how to use it, I'm trying to check if a variable, which contains a string, consists of only spaces, tabs and newlines. How would I use issppace() as I'm confused with it always being False?.</p>

<p>Help would be much appreciated.</p>
