Extract all the info into a dictionary taking 'provider name' as key, and a list of 'address' and 'phone'

as value. Print out the dictionary, so we have a small 'database'.

$$ Count the item numbers inside this dictionary. Ask the user to input the provider's name, if the

provider is in the database, print out the corresponding address and phone numbers. Otherwise, ask

the user to input correct names and try again.
