Assert two variables are almost equal in python

Question

Here are two variables: earnings_forecast, actual_earning (numerical variables)

I want to assert if both these variables are equal with a diffe

Answer 1

Simple approach:

a, b = sorted(map(float, (a, b)))
assert a + abs(a)*1.02 >= b

You can use a custom Testcase subclass for use in tests:

class FooTestCase(TestCase):
    def assertAlmostEqual(a, b):
        a, b = sorted(map(float, (a, b)))
        self.assertTrue(a + abs(a)*1.02 >= b)
