Grabing email from a class with input from name

[Nickd12]

I'm wondering if there is a way where I can grab where I can grab an email from a class with in put from a name I know I can do this from making a list with the contact from the class but I have been driving myself crazy because I'm basically making a contact list twice and I feel like there definite has to be a better way 

so basically from the code I will import as an example I want to have an input like input("send to: ") and I type in John Doe and get his email from the Contact class so I can use it for smtplib

class Contacts:
    contactCont= 0
    def __init__(self, first_name,last_name, email):
        self.first_name=first_name
        self.last_name=last_name
        self.email=email

        Contacts.contactCont +=1
    def display_contact(self):
        print("First Name:", self.first_name, self.last_name, ", Email:", self.email)

john = Contacts("john", "Doe", "[email protected]")

this is what I'm using right now to retrieve the email but I'm making a list instead of grabbing directly from the class I want to eliminate this step if possible 

 
def contact_list():
    x = input("send to: ")
    contact_list_names = ["john",]
    contact_list_info = [Contacts.john.email,]
    return contact_list_info[contact_list_names.index(x)]
