How to print this class variable?

Question

If I try to print a class variable, which is a list, I get a Python object. (These are the examples I found in stackoverflow).

 class Contacts:
    all_contacts = []

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

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

c1 = Contacts("Grace", "[e-mail]")
print(c1.all_contacts)

[<__main__.Contact object at 0x0287E430>, <__main__.Contact object`

But in this simpler example, it does print:

class Example():
    samplelist= [1,2,3]

test= Example()
print (test.samplelist)
[1, 2, 3]

I realized that this line is the culprit: Contact.all_contacts.append(self)in the first code example. But I'm not quite sure what is going on here.

EDIT:

Several users told me to simply add self.nameinstead self.

So when I do this:

class Contacts:
   all_contacts = []

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

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

   def __repr__(self):
      return str(self)

c1 = Contacts("Paul", "[e-mail]")
c2 = Contacts("Darren", "[e-mail]")
c3 = Contacts("Jennie", "[e-mail]")

print(Contacts.all_contacts)

I get:

['Paul', '[e-mail]', 'Darren', '[e-mail]', 'Jennie', '[e-mail]']

Instead:

[Paul, <[e-mail]>, Darren, <[e-mail]>, Jennie, <[e-mail]>]

Thus, formatting in a method __str__does not work here.

-

, , 6, , __repr__.

Answer 2

, :

Contacts.all_contacts.append(self)

self all_contacts.

- , - all_contacts.

Answer 3

python str (all_contacts), .

python .
