In Python, a set is an unordered collection of unique elements. It is similar to a list or a tuple, but unlike those data types, a set does not allow duplicate values. Sets are implemented using a hash table, which allows for fast membership testing and set operations such as intersection and union.
To create a set in Python, you can use curly braces {} or the built-in set() function. For example:
Sets are one of the 4 built-in data types in Python; it is an unordered collection data type that is iterable, mutable, and does not allow for duplicate elements.
Example:
The advantage of using a set as opposed to a list is that it uses a hash table for performing set operations, which is more optimized.
Sets are unordered, as a result of which items cannot be accessed using indexes as in the case of lists. However, we can loop through the items using a loop.
Example:
We can add elements to a set as follows:
To remove a specific element:
To clear all elements from the set:
