Explanation

While 'ليس' (laysa) is grammatically correct for 'not', it's more formal and less commonly used in everyday speech and especially in technical contexts. 'لا' (la) is a more natural and frequently used negation in Gulf Arabic, and is more appropriate for a programming operator. It's also shorter.
