Data Science and Machine Learning (Theory and Projects) A to Z - Sets: Definition of Set Exercise 01

The video tutorial explores the definition of a set, questioning whether a set can contain different types of objects. It provides examples of sets with integers and strings, and poses the question of whether a set can have heterogeneous objects, such as numbers and strings together. The video concludes by encouraging viewers to revisit the definition of a set to determine if mixed object types are permissible.

What is a key characteristic of a set as introduced in the first section?

• All objects must be identical.

• Objects can be of different types.

• No two objects are the same.

• Objects must be in alphabetical order.

In the context of sets, what does the term 'string class' refer to?

• A set with no elements.

• A set with mixed data types.

• A set containing only strings.

• A set containing only numbers.

Which of the following is an example of a homogeneous set?

• A set containing 1, 'prob', and 2.996.

• A set with 'apple', 3, and 'banana'.

• A set with 'dog', 'cat', and 5.

• A set containing 'math', 'science', and 'history'.

What is the main question posed in the final section?

• Can a set have heterogeneous objects?

• Are sets always finite?

• Can a set contain only numbers?

• Do sets need to be ordered?

What should you do to determine if a set can have heterogeneous entries?

• Revisit the definition of a set.

• Ignore the definition of a set.

• Assume all sets are homogeneous.

• Consult a dictionary.
