What is `quote>` prompt?

The quote> prompt typically indicates that you are in a multi-line input mode in a programming environment or REPL (Read-Eval-Print Loop) where you are expected to provide a block of code or a string that spans multiple lines. It usually appears when you start a multi-line string or a block of code but haven't completed it yet. To exit this prompt, you would typically complete the input or cancel it, depending on the environment you are using.
