python random seed time
import random from datetime import datetime random.seed(datetime.now()) ..., According to the documentation for random.seed : If x is omitted or None, current system time is used; current system time is also used to initialize the generator when the module is first imported. If randomness sources are provided by the operating sys, Pseudo-random number generators work by performing some operation on a value. Generally this value is the previous number generated by the generator. However, the first time you use the generator, there is no previous value. Seeding a pseudo-random numbe, Actually I was wrong. It's possible to do it: Here's how: import time import random def predicite_future(delay): random.seed(long(time.time() + delay) * 256) return random.random() delay = 10 print "The next value will be:",predicite_fu, Your friend is dead wrong, and would know so if he read the documentation for the seed() function: Initialize the basic random number generator. Optional argument x can be any hashable object. If x is omitted or None, current system time is used; current, Edit: my logic was off... woops. Answer is still the same. random.seed(time.time()) seems to use the rounded number produced by time.time() . a = time.time() # say print(a) produces 1234567890.123456 b = 1234567890.123456 random.seed(a) # this will produ
