Ingredients

First, we need meat. Let’s say we have ham and turkey.

meat

['ham', 'turkey']

We use index to choose one from the list. For instance, we can use 0 for ham and 1 for turkey.

meat[0]

'ham'

meat[1]

'turkey'

Then, we choose what kind of bread we want. We have white or potato.

bread

['white', 'potato']

Same pattern applies for choosing bread.

bread[1]

'potato'

Lastly, we choose either pepperjack or cheddar cheese.

cheese

['pepprjack', 'cheddar']

cheese[0]

Comparison operators

We can check equality of sandwiches.

test_eq(Sandwich(meat=1, bread=0, cheese=1), Sandwich(meat=1, bread=0, cheese=1))
test_eq(Sandwich(meat=0, bread=0, cheese=1), Sandwich(meat=0, bread=0, cheese=1))

test_ne(Sandwich(meat=1, bread=1, cheese=0), Sandwich(meat=1, bread=1, cheese=1))
test_ne(Sandwich(meat=1, bread=1, cheese=1), Sandwich(meat=0, bread=0, cheese=0))
