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:

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

Let's extract the last element from the dictionary:

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

And this element will disappear from the dictionary:

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

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

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