Just like lists and tuples, Python also provides another way to store multiple items: sets. Sets are useful when we want only unique values. Sets are unordered collections of data items. They store multiple items in a single variable. Set items are separated by commas and enclosed within curly brackets {}. Sets are mutable, meaning you can add or remove items, but you cannot change an existing item because set items must be immutable.

Example:

info = {"Carla", 19, False, 5.9, 19}
print(info)

Output:

{False, 19, 5.9, 'Carla'}

Here we see that the items of a set occur in random order and hence they cannot be accessed using index numbers. Also, sets do not allow duplicate values.

Accessing set items:

Using a For loop

You can access items of a set using a for loop.

Example:

info = {"Carla", 19, False, 5.9}
for item in info:
    print(item)

Output:

False
Carla
19
5.9
