How to check and see if an output contains the desired elements from any list or not?

Question

I am trying to write tests for a particular app in django using the python's unittest library.

def test_permissions_for_admin(self):
    admin = Group.objects.get(name='Administrator')
    permisisons = admin.permissions.all()
    admin_permissions = ['add_ipaddress', 'change_ipaddress', 'delete_ipaddress', 'view_ipaddress', 'add_subnet', 'change_subnet', 'delete_subnet', 'view_subnet']
    
    for p in permissions:
        print(p.codename)
    
    for p in permissions:
        self.assertIn(p.codename, admin_permissions)

The Above code prints this, OUTPUT:

change_emailaddress
delete_emailaddress
view_emailaddress
add_ipaddress
change_ipaddress
delete_ipaddress
view_ipaddress
add_subnet
change_subnet
delete_subnet
view_subnet
view_group
change_organization
change_organizationowner
add_organizationuser
change_organizationuser
delete_organizationuser
view_organizationuser
add_user
change_user
delete_user
view_user

Whereas What I am trying to check is that, all the permissions present from the variable admin_permissions are present in this output or not.

I have tried using the assertIn, assertEqual, & assertTrue methods but it doesn't seem to work here. Is there anything else I could look for or any method present which I am not aware of to solve such kind of issues.

If you want to check if the admin has all the permissions, you need to do this the other way around, so:

perms = list(admin.permissions.values_list('codename', flat=True))
for p in admin_permissions:
    self.assertIn(p, perms)

we here thus check that for each item in admin_permissions, it is a member of perms: the codenames of the .permissions of admin.
