Concept: Tuples

Tuples are an ordered and immutable collection of items. Because tuples are immutable, they cannot be modified after they are created. This means that you cannot add, remove, or change items in a tuple.

Tuples are created with parentheses () instead of brackets.

ftp_uri = f"ftp://{ftp_socket[1]}:{ftp_socket[2]}"
