random.seed(): What does it do?

Question

I am a bit confused on what random.seed() does in Python. For example, why does the below trials do what they do (consistently)?

>>> i         


        

Answer 1

In this case, random is actually pseudo-random. Given a seed, it will generate numbers with an equal distribution. But with the same seed, it will generate the same number sequence every time. If you want it to change, you'll have to change your seed. A lot of people like to generate a seed based on the current time or something.
