# Sets are used to store multiple items in a single

# variable.

# A set is a collection which is unordered,

# unchangeable, and unindexed.

# Note: Set items are unchangeable,

# but you can remove items and add new items.

thisset = {"apple", "banana", "cherry", "apple"}

# NB Duplicate item is just ignored

print(thisset)

# New items added

thisset.add("orange")

# or one-by-one with no guaranteed order

for x in thisset:

  print(x)
