I had the same issue with unit-test, testing a method that returns a dict containing floats.

assertAlmostEqual did almost what I needed and I made it work it by comparing the values of my returned dict with the values of the expected dict using a generator comprehension:

import unittest


class TestAlmostEqual(unittest.TestCase):

    def method_to_be_tested(self):
        return {"A":1.035, "B":3.074, "C":5.777}

    def test_almost_equal(self):
        result = self.method_to_be_tested().values()
        expected = {"A":1.030, "B":3.073, "C":5.779}.values()
        generator = (value for value in expected)

        for val in result:
            self.assertAlmostEqual(val, next(generator), places=2)

Should work from python 3.6+ since dictionaries became ordered.

I'm relatively new to python so please tell me if I'm mistaken or messing something up.
