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 the items will appear in a random order.

Access Items

You cannot access items in a set by referring to an index, since sets are unordered the items has no index.

But you can loop through the set items using a for loop, or ask if a specified value is present in a set, by using thein keyword.

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

for x in thisset:
  print(x)

Output

Change Items

Once a set is created, you cannot change its items, but you can add new items.

Add Items

To add one item to a set use the add() method.

To add more than one item to a set use the update() method.

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

thisset.add("orange")

print(thisset)
