The major difference is that sets, unlike lists or tuples, cannot have multiple occurrences of the same element and store unordered values. Lists and tuples have many similarities. In python lists **comes under mutable objects and **tuples comes under immutable objects. This Python Data Structure is like a, like a list in Python, is a heterogeneous container for items. Lists are defined very similarly to tuples. Put away your binding equipment, it isn't that advanced. Your brain still hurting from the last lesson? 25, Sep 20.

Advantages of Python Sets Lists and tuples are standard Python data types that store values in a sequence. So Python just needs to allocate enough memory to store the initial elements.

Empty tuple acts as a singleton, that is, there is always only one tuple with a length of zero. Tuples like strings are immutables. The major difference is that sets, unlike lists or tuples, cannot have multiple occurrences of the same element and store unordered values. Lists need not be homogeneous always which makes it the most powerful tool in Python.The main characteristics of lists are – The list is a datatype available in Python which can be written as a list of comma-separated values (items) between square brackets.
