The video tutorial covers the creation and manipulation of dictionaries in Python. It explains how to create a dictionary using keys and values, assign default values, and update values using slicing and indexing. The tutorial also demonstrates built-in dictionary functions like pop, update, and clear. The session concludes with a summary of the methods discussed and a preview of the next lesson on loops.

What is the default value assigned to keys when using the 'fromkeys' method without specifying a value?

• False

• Empty string

• None

• 0

How can you update the value of a specific key in a dictionary?

• By using the key as an index

• By using the 'update' method

• By using the 'append' method

• By using the 'remove' method

Which method is used to remove a key-value pair from a dictionary?

• delete

• discard

• remove

• pop

What happens when you use the 'clear' method on a dictionary?

• It removes a specified key-value pair

• It removes the last key-value pair

• It removes all key-value pairs

• It removes the first key-value pair

How can you add a new key-value pair to an existing dictionary?

• By using the 'update' method

• By using the 'insert' method

• By using the 'append' method

• By using the 'add' method
