5. What if you want to check for combinations of set values? Suppose that you want to find any drink that has orange juice or vermouth? Let’s use the set intersection operator, which is an ampersand (&): >>> for name, contents in drinks.items(): ... if contents & {'vermouth',...

It’s the part of the green line passing through the gray area from the intersection point with the blue line to the intersection point with the red line. The latter point is the solution. If you insert the demand that all values of x must be integers, then you’ll get a mixed-...
