Python In Practice - 15 Projects to Master Python - Sets Built-In Functions

The video tutorial covers built-in set functions in Python, including adding, removing, clearing, and updating elements in a set. It explains the use of the dot operator for adding elements, the remove and discard functions for removing elements, and the clear and update functions for managing set contents. The tutorial also highlights the limitations of concatenating sets and concludes with a preview of mathematical set operations.

What function is used to add an element to a set in Python?

• push()

• insert()

• add()

• append()

Which function should you use to remove an element from a set without causing an error if the element is not present?

• pop()

• delete()

• remove()

• discard()

What happens if you try to remove an element that is not in the set using the remove function?

• The set is cleared

• A KeyError is raised

• The element is ignored

• The set is updated

Which function is used to clear all elements from a set?

• empty()

• reset()

• delete()

• clear()

Why can't sets be concatenated using the '+' operator?

• Sets are immutable

• Sets do not support concatenation

• Sets can only be concatenated with lists

• Sets require a special function for concatenation
