The function first checks whether the Global Variable contacts is empty or not, if it is, it notifies the user to add a new contact and try again.
"You don't have any contacts saved! Consider adding a few new contacts."
Elsewise, an indefinite while loop iterates, where it prints all the saved contacts:
print("\n-------- Your Contacts --------")
for item in contacts: # prints all the contacts
print(f'> {item}')Further it asks the user to choose between deleting a specific contact, or deleting all the saved contacts at once
Enter the name of the Contact you want to delete
[Write 'DEL_ALL' to delete all of your existing contacts]:
If the user chooses to delete all the contacts at once, it asks for confirmation.
You are about to delete all of your contacts after this command, if you really wish to, write "CONFIRM":
Elsewise if the user enters a contact name from the contact list, it deletes the key:value pair of that particular contact from contacts.
After deleting the contact(s), it asks the user whether they want to delete another contact.
Do you want to delete another contact (y/n) ?:
Further it checks whether contacts is empty or not, if it is not, the whole process iterates again.
