How to pass list for testing in python?

I have create two dict.

self.post_data={

'name' : 'Org 1',

'url' : 'http://www.org1.com',

'summary' : 'This is an example org1'

}

second

self.post_data1={

'name' : 'Org 2',

'url' : 'http://www.org2.com',

'summary' : 'This is an example org2'

}

Now my test_post_list function

def test_post_list(self):

    self.create_session()
    self.assertEqual(Org.objects.count(), 0)
    self.assertHttpCreated(self.api_client.post('/members/api/v1/org/', format='json', data={self.post_data,self.post_data1}))
    self.assertEqual(Org.objects.count(), 1)

if i pass data like this it raises an error

>ERROR: test_post_list (members.tests.test_org_resource.OrgTest)

Traceback (most recent call last):

File "C:\Users\Sanky\amber\members\tests\test_org_resource.py", line 51, in te st_post_list

self.assertHttpCreated(self.api_client.post('/members/api/v1/org/', format='

json', data={self.post_data,self.post_data1}))

TypeError: unhashable type: 'dict'`

how i pass list as data to test function..
