Instruction
Very good! Let's do some more exercises.
Exercise
We defined a list of some popular UK supermarkets in a variable called (surprise, surprise) supermarkets.
Write some code that will do the following: if 'Lidl' is not in the list, add it to the list.
Hint: the negation of if item in list is if item not in list.
Stuck? Here's a hint!
Use list.append(item) and:
if 'Lidl' not in supermarkets: # code here
