Python Sets

Sets are unordered collection of data items. They store multiple items in a single variable. Sets items are separated by commas and enclosed within curly brackets {}. Sets are unchangeable, meaning you cannot change items of the set once created. Sets do not contain duplicate items.

 

Example:

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

Output:

{False, 19, 5.9, 'Carla'}

 

Here we see that the items of 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 set using a for loop. 

Example:

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

Output:

False
Carla
19
5.9
