How to pass variables from setup to tests in nosetest?

With python and nosetests I have the following setup:

- package
    - __init__.py
    - test1.py
    - test2.py

The __init__.py module contains a set up function

def setup():
    print("Setup called")
    var = 42

which will be used later to create a unique identified (different between running the tests, but the same for all the tests inside the package).

How can the tests itself access this variable (in this example case var)? The test scripts are just some stubs:

from nose.tools import assert_true

class TestSuite(object):
    def test1(self):
        # How to get content of 'var' here?
        assert_true(True)

Is there some pythonic way to do this, or just use an environment variable to do this?

nose calls .setup() methods inside classes:

class Test:
    def setup(self):
        self.var = 1

    def test_print_var(self):
        print(self.var)

This also applies to methods inherited from elsewhere:

class TestBase:
    def setup(self):
        self.var = 1

class Test(TestBase):
    def test_print_var(self):
        print(self.var)
