The Complete Python Course - Sets - 15 Coding Example

This video tutorial covers the basics of Python sets, including creating sets with various data types, looping through sets, accessing and adding items, updating and removing items, clearing and deleting sets, joining sets, finding differences, using intersection and symmetric difference methods, and copying and finding the union of sets.

What is a characteristic of a Python set?

• It allows duplicate values.

• It is immutable.

• It is unordered.

• It is ordered.

Which method is used to loop through a set in Python?

• for loop

• while loop

• foreach loop

• do-while loop

How can you check if an item exists in a Python set?

• Using the 'in' keyword

• Using the 'exists' function

• Using the 'contains' method

• Using the 'has' method

Which method is used to add an item to a Python set?

• push()

• add()

• append()

• insert()

What happens if you try to remove an item not present in a set using the remove() method?

• The set is updated.

• The set is cleared.

• An error is raised.

• The item is ignored.

Which method can be used to clear all items from a set?

• clear()

• delete()

• discard()

• remove()

How can you join two sets in Python?

• Using the join() method

• Using the merge() method

• Using the union() method

• Using the append() method

Which method is used to find the difference between two sets?

• difference()

• subtract()

• exclude()

• remove()

What does the intersection_update() method do?

• Removes all items from a set

• Keeps only items present in both sets

• Adds all items from another set

• Finds the difference between two sets

How can you create a copy of a set?

• Using the replicate() method

• Using the clone() method

• Using the copy() method

• Using the duplicate() method
