Python Program to Delete an Element From a Dictionary

In this example, you will learn to delete an element from a dictionary.

To understand this example, you should have the knowledge of the following Python programming topics:

• Python Dictionary
• Python del Statement
• Python Dictionary pop()

1. Example 1: Using del keyword

my_dict = {31: 'a', 21: 'b', 14: 'c'}

del my_dict[31]

print(my_dict)

Output

{21: 'b', 14: 'c'}

In the code above, the key:value pair with key as 31 is deleted using del keyword. del keyword gives a KeyError if the key is not present in the dictionary.

2. Example 2: Using pop()

my_dict = {31: 'a', 21: 'b', 14: 'c'}

print(my_dict.pop(31))

print(my_dict)

Output

a
{21: 'b', 14: 'c'}

Pass the key 31 as an argument to the pop() method. It deletes the key:value pair with key as 31 as shown in the output.

pop() also returns the value of the key passed.
