| In https://docs.python.org/2/library/random.html#random.seed I can find that "If a hashable object is given, deterministic results are only assured when PYTHONHASHSEED is disabled." Both int and long are hashable. However, tests on the random module as well as C source code of random_seed (as indicated in http://stackoverflow.com/a/41228062/4879688) suggest that behaviour of the module is deterministic when seeded with an integer. | ||
