Each Answer to this Q is separated by one/two green lines.
If I use the Python function
random.seed(my_seed) in one class in my module, will this seed remain for all the other classes instantiated in this module?
Yes, the seed is set for the (hidden) global
Random() instance in the module. From the documentation:
The functions supplied by this module are actually bound methods of a hidden instance of the
random.Randomclass. You can instantiate your own instances of
Randomto get generators that don’t share state.
Random() instances if you need to keep the seeds separate; you can pass in a new seed when you instantiate it:
>>> from random import Random >>> myRandom = Random(anewseed) >>> randomvalue = myRandom.randint(0, 10)
The class supports the same interface as the module.
