To actually generate a pseudo-random number, you call the generator’s .random() method. To satisfy yourself that the code is indeed generating a random number, run it several times and notice that you get a different number each time. Remember, this is because the seed value passed will ...
If you run this code yourself, I’ll bet my life savings that the numbers returned on your machine will be different. The default when you don’t seed the generator is to use your current system time or a “randomness source” from your OS if one is available.With random.seed(), you...
