2.0 Python: Access Set Items

2.1 Access Items

You cannot access items in a set by referring to an index or a key.

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 the in keyword.

2.1.1 Example

Loop through the set, and print the values:

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

for x in thisset:
    print(x)

2.1.2 Example

Check if "banana" is present in the set:

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

if 'banana' in thisset:
    print('"banana" in thisset')

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

print("banana" in thisset)

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

print(f'Is "banana" in thisset? {"banana" in thisset}')

2.1.3 Example

Check if "banana" is NOT present in the set:

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

print("banana" not in thisset)

note

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