How to Access Items in a Python Set

Learn how to work with Python sets by accessing items. Discover that sets do not support indexing or key-based access, but you can loop through items using a for loop or check for item presence using the in keyword.

Python - Access Set Items

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.

  thisset = {"orange", "grape", "mango"}
  
  for x in thisset:
    print(x)
              

  orange
  grape
  mango
              

Example

Check if "grape" is present in the set:

  thisset = {"orange", "grape", "mango"}
  
  print("grape" in thisset)
              

  True
              

Example

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

  thisset = {"orange", "grape", "mango"}
  
  print("banana" not in thisset)
              

  True
              

Change Items

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