Explanation:
a while loop is a condition-controlled loop. While loops continue no matter what under a certain condition, unless you insert the keyword <em>break.</em>
One example in python is this:
while x > y:
<em>pass</em>
The keyword to break a while loop may vary depending on the coding language you are using.
<u>Tip</u> The pass keyword allows a no error contact between loop and the terminal. Pass in a nutshell is almost as if saying nothing at all, but just leaving the condition blank. We only use pass because it prevents errors instead of no value.
