A dictionary containing phone numbers as keys and names as values is named mydict. Write a python program to delete the key value pair from this dictionary after accepting phone number from the user.
Answer:
#
Assume that mydict is a dictionary containing phone numbers as keys and names as values
# For example, mydict = {'1234567890': 'Alice', '0987654321': 'Bob', '1357924680': 'Charlie'}
# Ask the user to enter a phone number
phone = input("Please enter a phone number: ")
# Check if the phone number is in mydict
if phone in mydict:
# Delete the key-value pair using del or pop
del mydict[phone]
# Print a confirmation message
print(f"The phone number {phone} has been deleted from mydict.")
else:
# Print an error message
print(f"The phone number {phone} is not in mydict.")
