Is this really what you want (And similarly in your other test
method.)?  If I am reading things correctly, you are calling
red_temperature_simulation *twice*, which will *usually* give you two
*separate* values, which you then attempt to compare.  Shouldn't you
first do:

for i in range(100000):
    value_to_test = red_temperature_simulation()
    (self.assertLess(value_to_test, 100.0) <Which logic op?>
        self.assertGreater(value_to_test, 103.0))
?

If my understanding is indeed correct, then I will leave it to you to
figure out which logic operator ("and" or "or") makes sense here!
