Question: 1 / 20

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

dropitem()

popitem()

The method used to remove a key-value pair from a dictionary is indeed the popitem() method. In Python, dictionaries are a collection of key-value pairs, and popitem() specifically removes and returns the last inserted key-value pair in the dictionary as a tuple. This method is useful when you want to not only remove an item but also retrieve the item at the same time.

The other methods mentioned do not exist as standard dictionary methods in Python. This includes options that suggest the removal of items with names resembling dropitem(), removeitem(), or deleteitem(), which do not pertain to the operations defined for dictionaries in Python. Therefore, popitem() is the correct choice as it is a valid method that operates precisely as described in the context of dictionaries.

removeitem()
