Do you need a third variable to swap?

Short answer. No, not in Python.

What must match in multiple assignment?

The number of names and values.

Remember

Values match names in order
Right side is read first
Counts must match

Swap two values without a third variable? Yes. Line one sets tea to ten and coffee to twenty five. Line two reads the right side first. So the values swap. Values match names in order. The right is read first. Counts must match.
