In this tutorial, we’ll learn how to use Python dictionary popitem() method using proper Python code examples with step by step explanation.
Introduction: Python Dictionary popitem() Method
This method is used to remove/delete the last or latest item(key, value) inserted in Python dictionary.
Syntax of popitem() Method
dictionaryName.popitem()
- This method does not take any arguments.
- It removes and returns the last/latest item inserted in the specified Python dictionary.

{'a': 'Zeeshan', 'b': 'white'}As you can see here that the last item(key, value) is removed from the dictionary.
