) Write a program to input your friends' names and their Phone Numbers and storethem in the dictionary as the key-value pair. Perform the following operations on thedictionary: (3)i) Display the name and phone number of all your friendsii) Add a new key-value pair in this dictionary and display the modifieddictionaryiii) Delete a particular friend from the dictionaryiv) Modify the phone number of an existing friendv) Check if a friend is present in the dictionary or notvi) Display the dictionary in sorted order of name

Sure! Here is a step-by-step solution to the problem:

Step 1: Create an empty dictionary to store the friends' names and phone numbers. Step 2: Use a loop to input the names and phone numbers of your friends and add them as key-value pairs in the dictionary. Step 3: To display the name and phone number of all your friends, iterate over the dictionary and print each key-value pair. Step 4: To add a new friend's name and phone number, use the dictionary's "update" method to add a new key-value pair. Step 5: To delete a particular friend from the dictionary, use the "del" keyword followed by the key of the friend you want to delete. Step 6: To modify the phone number of an existing friend, use the dictionary's "update" method to update the value associated with the friend's key. Step 7: To check if a friend is present in the dictionary, use the "in" keyword followed by the key you want to check. Step 8: To display the dictionary in sorted order of name, use the "sorted" function with the dictionary's "items" method as the argument.

Here is an example implementation in Python:

# Step 1
friends_dict = {}

# Step 2
num_friends = int(input("Enter the number of friends: "))
for _ in range(num_friends):
    name = input("Enter friend's name: ")
    phone_number = input("Enter friend's phone number: ")
    friends_dict[name] = phone_number

# Step 3
print("Name and phone number of all friends:")
for name, phone_number in friends_dict.items():
    print(name, phone_number)

# Step 4
new_name = input("Enter new friend's name: ")
new_phone_number = input("Enter new friend's phone number: ")
friends_dict.update({new_name: new_phone_number})

# Step 5
delete_name = input("Enter the name of the friend you want to delete: ")
del friends_dict[delete_name]

# Step 6
modify_name = input("Enter the name of the friend whose phone number you want to modify: ")
new_phone_number = input("Enter the new phone number: ")
friends_dict.update({modify_name: new_phone_number})

# Step 7
check_name = input("Enter the name of the friend you want to check: ")
if check_name in friends_dict:
    print(check_name, "is present in the dictionary.")
else:
    print(check_name, "is not present in the dictionary.")

# Step 8
sorted_dict = dict(sorted(friends_dict.items(), key=lambda x: x[0]))
print("Dictionary in sorted order of name:")
for name, phone_number in sorted_dict.items():
    print(name, phone_number)

This program allows you to input your friends' names and phone numbers, perform various operations on the dictionary, and display the results accordingly.
