The Python pop() method and del keyword remove keys from a dictionary. pop() accepts the name of the key you want to remove from the dictionary as an argument. The del keyword stands on its own and refers to a specific key.<\/em><\/p>\n\n\n\n

Dictionaries are mutable objects. This means you can change the values dictionaries store. As a result, you can remove keys from dictionaries at any time if they are no longer needed.<\/p>\n\n\n\n

Suppose you have a Python dictionary<\/a> that stores information about books sold in a bookstore. You may decide to remove a key that denotes if the book has been on the manager’s recommended list.<\/p>\n\n\n\n

In this guide, we discuss how to remove a key from a Python dictionary. We\u2019ll walk through two examples so you can start removing dictionary keys quickly.<\/p>\n\n\n\n

Remove Key from a Dictionary Python: pop()<\/h2>\n\n\n\n

The Python pop() method removes an item from a dictionary.<\/p>\n\n\n\n

This method can also be used to remove items from a list at a particular index value. For this guide, we’ll focus on removing an item from a dictionary. Read our tutorial on the Python list pop() guide<\/a> for more information on how to remove an item from a list.<\/p>\n\n\n\n

The syntax for this method is:<\/p>\n\n\n\n

dictionary.pop(key_to_remove, not_found)<\/pre><\/div>\n\n\n\n
The pop() method can accept either one or two parameters:<\/p>\n\n\n\n
