Set

A set is a collection which is unordered and unindexed. In Python, sets are written with curly brackets.

thisset = {"apple", "banana", "cherry"}
print(thisset)

# Note: Sets are unordered, so you cannot be sure in which order the items will appear.

{'apple', 'cherry', 'banana'}

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

for x in thisset:
  print(x)

apple
cherry
banana

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

print("banana" in thisset)

True

# add items 

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

thisset.add("orange")

print(thisset)

{'apple', 'cherry', 'orange', 'banana'}
