Sure. a,b = b, a+b is equivalent to: new_a = b new_b = a + b a = new_a b = new_b del new_a del new_b That is, we first evaluate everything on the right hand side of the equals sign, then assign those values to a and b. Then we get rid of the temporary variables, since the original statement didn't leave any temporary variable floating around. -- Jerry _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
