Extracting the Last Element in Python

The popitem method can be used to retrieve the last item from a dictionary. It returns a tuple of key-value pairs of the retrieved item.

Let's try it in practice. Let's say we have the following dictionary:

dct = {
	'a': 1,
	'b': 2,
	'c': 3
}

Let's extract the last element from the dictionary:

print(dct.popitem()) # ('c', 3)

And this element will disappear from the dictionary:

print(dct) # {'a': 1, 'b': 2}

Given a dictionary:

dct = {
	'x': 1,
	'y': 2,
	'z': 3
}

Get a tuple from it of the last element with the key, removing it from the dictionary.

Given a dictionary:

dct = {
	1: 'a',
	2: 'b',
	3: 'c',
	4: 'd',
	5: 'e'
}

Write the code to get the following result:

[5, 4, 3, 2, 1]
