You have probably had the chance to iterate through a list of elements in one way or another, or through elements of a set, or a dictionary. We can go through a list, a set, or a dictionary and access their elements because they are iterable objects.
An iterator is an object that contains a countable number of objects. This means that you can iterate through elements that an iterator contains.

Sometimes, you may need to check whether a list has any duplicate elements. This can be a common task when you are given a list of numbers or a list of strings. This can also be something that you may need to do both at work, or it can also be part of a coding challenge that you are implementing when being asked at a programming interview.

If you need to find whether 2 sets have the same elements, then you need to use an operation such as intersection.
This operation is known in Math and used everywhere. In Python, we have 2 built-in methods that we can use right away to find whether 2 sets have the same elements or not.

Most of the time you are adding elements into a list, or set, or a dictionary. However, there can also be cases when you just need to remove elements. Maybe a particular element, or even all elements at once.
If that is the case, then there is a quick method in Python that you can use to do that.
