Exchange two numbers in place

Python provides an intuitive way to assign and exchange values (variable values) in one line of code, as shown in the following example:

XMagna y = 10, 10, 20 print (x, 10), y, 1, (10, 20), 2, 10)

A new tuple is formed on the right side of the assignment, and the left immediately parses (unpack) that (unreferenced) tuple to the variable sum.

Once the assignment is complete, the new tuple becomes unreferenced and marked as garbage collected, and the variable exchange is finally completed.
