How to exit multiline mode?

To exit multiline mode in the Python interpreter, you can do the following:

1. Complete the Block: If you are in the middle of a block (like a function or loop), you can finish the block by providing the necessary indentation and then pressing Enter. For example, if you are defining a function, make sure to complete it properly.

2. Use a Blank Line: If you are in the middle of typing a multiline statement and want to exit, you can simply press Enter on a blank line. This will indicate to the interpreter that you are done with the current block.

3. Interrupt the Session: If you want to exit the interpreter entirely, you can type exit() and press Enter, or press Ctrl+D on Unix/Linux systems.

Make sure to complete any open blocks before trying to exit to avoid syntax errors.
