How do I print the actual contents of this list

The code is short and simple:

class Contact:
    all_contacts = 开发者_开发问答[]

    def __init__(self, name, email):
        self.name = name
        self.email = email
        Contact.all_contacts.append(self)


c1 = Contact("Paul", "something@hotmail.com")
c2 = Contact("Darren", "another_thing@hotmail.com")
c3 = Contact("Jennie", "different@hotmail.com")


for i in Contact.all_contacts:
    print(i)

Clearly all I want to do is print the 'all_contacts' list with the info I have added, but what I get is:

<__main__.Contact object at 0x2ccf70>
<__main__.Contact object at 0x2ccf90>
<__main__.Contact object at 0x2ccfd0>

What am I doing wrong?

Add the following to your Contact class:

class Contact:
    ...
    def __str__(self):
        return '%s <%s>' % (self.name, self.email)

This will tell Python how to render your object in a human-readable string representation.

Reference information for str

The __repr__ and __str__ methods for Contact aren't defined, so you get this default string representation instead.

def __str__(self):
    return '<Contact %s, %s>' % (self.name, self.email)

1. Separate the container from the items stored in the container.

2. Add a __str__() method to Contact.

   class Contact:
       def __init__(self, name, email):
           self.name = name
           self.email = email
       def __str__(self):
           return "{} <{}>".format(self.name, self.email)
   
   class ContactList(list):
       def add_contact(self, *args):
           self.append(Contact(*args))
   
   c = ContactList()
   c.add_contact("Paul", "something@hotmail.com")
   c.add_contact("Darren", "another_thing@hotmail.com")
   c.add_contact("Jennie", "different@hotmail.com")
   
   for i in c:
       print(i)
