Example 1: Using del keyword
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.
Example 2: Using pop()
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.
