Set Data Type that Does Not Allow Duplicate Values

A Set is a data type that does not allow duplicate values, making it useful for removing duplicates from data or performing mathematical set operations.

Since Set does not maintain the order of elements, you cannot use an index to directly access a specific position like you would with an array.

You can declare a set using {} or the set() function.

Any duplicate values within the declared set will be automatically removed.

Copy
numbers = {1, 2, 2, 3}

print(numbers)  # {1, 2, 3}

Copy
my_set = set([1, 2, 3, 3, 3])

print(my_set)  # {1, 2, 3}
