What is the difference between tuples and sets in Python?

Tuples and sets are two distinct data structures that have the following differences in Python.

1. Tuples are ordered collections, the order of elements remains the same once created. Sets, on the other hand, are unordered and the order of elements is not guaranteed.
2. Tuples are represented using parentheses (), for example (1, 2, 3), while sets are represented using curly braces {}, for example {1, 2, 3}.
3. Elements in a tuple can be repeated, for example (1, 2, 2), but elements in a set are unique and do not allow duplicates.
4. Tuples are immutable data structures, meaning once they are created, the elements in a tuple cannot be changed, added, or removed. On the other hand, sets are mutable and allow for operations such as adding or removing elements from the set.

In general, tuples are suitable for storing data of fixed length and in order, while sets are suitable for storing unique data and have better performance in terms of quick search and de-duplication of data.
