How to extract parameters stored in mock.call

I am unit testing the following functions:

import uuid


def process_name(id, name, weight):
    print('process_item:', id, name, weight)


def process_list(names):
    for (name, weight) in names:
        id = uuid.uuid4()
    process_name(id, name, weight)

My unit test looks as follows:

import unittest
from mock import patch, call
import SomePackage.SomeModule


class MyTestCase(unittest.TestCase):
    def test_something(self):
        items = [('Joe', 190), ('Dan', 200)]
        with patch('SomePackage.SomeModule.process_name') as mock_process_name:
            SomePackage.SomeModule.process_list(items)

I cannot match the whole mock_calls thing, because the first parameter submitted to it is a guid, and as such it will be different every time I call the function:

print(mock_process_name.mock_calls)
[call(UUID('some randomish guid'), 'Joe', 190),
 call(UUID('some other guid'), 'Dan', 200)]

I want to extract the parameters, and only match the non-volatile ones:

 print(mock_process_name.mock_calls[0][1][1:])
 print(mock_process_name.mock_calls[1][1][1:])
 ('Joe', 190)
 ('Dan', 200)

I know that I can also mock the thing which returns guids, and provide a fixed list of values in its side_effect. However, I feel quite lazy needing to mock too many things like uuid.uuid4(), datetime.now() and such. This is why I am looking for an alternative to mocking each and every volatile function.

Is there a more readable alternative to mock_calls[0][1][1:]?
