Python Program for Dictionary popitem() Method

In the previous article, we have discussed Python Program for Dictionary keys() Function
Dictionary in python :

A dictionary is a set of elements that have key-value pairs. The values in the elements are accessed using the element’s keys.

Examples:

Example1:

Input:

Given dictionary = {'hello': 120, 'this': 130, 'is': 140, 'btechgeeks': 150}

Output:

The above given dictionary is :
{'hello': 120, 'this': 130, 'is': 140, 'btechgeeks': 150}
The key-value pair removed from the given dictionary= ('btechgeeks', 150)
The above given dictionary after the removal of the last item(key-value):
{'hello': 120, 'this': 130, 'is': 140}

Example2:

Input:

Given dictionary = {10: 'good', 60: 'morning', 140: 'btechgeeks'}

Output:

The above given dictionary is :
{10: 'good', 60: 'morning', 140: 'btechgeeks'}
The key-value pair removed from the given dictionary= (140, 'btechgeeks')
The above given dictionary after the removal of the last item(key-value):
{10: 'good', 60: 'morning'}

Program for Dictionary popitem() Method in python

Using Built-in Functions (Static Input)
Using Built-in Functions (User Input)

Dictionary popitem() Function:

Python popitem() is a Dictionary function that removes the most recently inserted key-value pair and prints the removed pair.

Syntax:

dictionary.popitem()

Parameter Values:

The dictionary popitem() function doesn’t have any parameters.

Method #1: Using Built-in Functions (Static Input)

Approach:

Give the dictionary as static input by initializing it with some random values and store it in a variable.
Print the above-given dictionary.
Apply dictionary.popitem() method to the above-given dictionary to remove the last inserted key-value pair.
Store it in another variable.
Print the above removed key-value pair.
Print the above-given dictionary after removal of the last item (key-value pair).
The Exit of Program.

Below is the implementation:

# Give the dictionary as static input by initializing it with some random values
# and store it in a variable.
gvn_dictinry = {'hello': 120, 'this': 130, 'is': 140, 'btechgeeks': 150}
# Print the above-given dictionary.
print("The above given dictionary is :")
print(gvn_dictinry)
# Apply dictionary.popitem() method to the above-given dictionary to remove the last
# inserted key value pair
# Store it in another variable.
remvd_lstitem = gvn_dictinry.popitem()
# Print the above removed key-value pair.
print("The key-value pair removed from the given dictionary=", remvd_lstitem)
# Print the above-given dictionary after removal of last item.
print("The above given dictionary after the removal of the last item(key-value):")
print(gvn_dictinry)

Output:

The above given dictionary is :
{'hello': 120, 'this': 130, 'is': 140, 'btechgeeks': 150}
The key-value pair removed from the given dictionary= ('btechgeeks', 150)
The above given dictionary after the removal of the last item(key-value):
{'hello': 120, 'this': 130, 'is': 140}

Method #2: Using Built-in Functions (User Input)

Approach:

Take a dictionary and initialize it with an empty dictionary using dict() or {}.
Give the number of keys as user input using int(input()) and store it in a variable.
Loop till the given number of keys using for loop.
Inside the for loop scan the key and value as user input using input(), split() functions, and store them in two separate variables.
Initialize the key with the value of the dictionary.
Print the above-given dictionary.
Apply dictionary.popitem() method to the above-given dictionary to remove the last inserted key-value pair.
Store it in another variable.
Print the above removed key-value pair.
Print the above-given dictionary after removal of the last item (key-value pair).
The Exit of Program.

Below is the implementation:

# Take a dictionary and initialize it with an empty dictionary using dict() or {}.
gvn_dictinry = {}
# Give the number of keys as user input using int(input()) and store it in a variable.
numb_of_kys = int(
    input('Enter some random number of keys of the dictionary = '))
# Loop till the given number of keys using for loop.
for p in range(numb_of_kys):
        # Inside the for loop scan the key and value as
    # user input using input(),split() functions
    # and store them in two separate variables.
    keyy, valuee =  input(
        'Enter key and value separated by spaces = ').split()
    # Initialize the key with the value of the dictionary.
    gvn_dictinry[keyy] = valuee

# Print the above-given dictionary.
print("The above given dictionary is :")
print(gvn_dictinry)
# Apply dictionary.popitem() method to the above-given dictionary to remove the last
# inserted key value pair
# Store it in another variable.
remvd_lstitem = gvn_dictinry.popitem()
# Print the above removed key-value pair.
print("The key-value pair removed from the given dictionary=", remvd_lstitem)
# Print the above-given dictionary after removal of last item.
print("The above given dictionary after the removal of the last item(key-value):")
print(gvn_dictinry)

Output:

Enter some random number of keys of the dictionary = 3
Enter key and value separated by spaces = 10 good
Enter key and value separated by spaces = 60 morning
Enter key and value separated by spaces = 140 btechgeeks
The above given dictionary is :
{'10': 'good', '60': 'morning', '140': 'btechgeeks'}
The key-value pair removed from the given dictionary= ('140', 'btechgeeks')
The above given dictionary after the removal of the last item(key-value):
{'10': 'good', '60': 'morning'}
