The "seed" is used to initialize the internal pseudo-random number generator. And providing a fixed seed assures that the same series of calls to ‘RandomState’ methods will always produce the same results, which can be helpful in testing.

The number "42" was apparently chosen as a tribute to the "Hitch-hiker's Guide" books by Douglas Adams, as it was supposedly the answer to the great question of "Life, the universe, and everything" as calculated by a computer (named "Deep Thought") created specifically to solve it.

For more details on the method itself, see the NumPy documentation page for RandomState.
