random() module is used to generate random numbers in Python. Not actually random, rather this is used to generate pseudo-random numbers. That implies that these randomly generated numbers can be determined.
random.getstate()
The getstate() method of the random module returns an object with the current internal state of the random number generator. This object can be passed to the setstate() method to restore the state. There are no parameters passed in this method.
Example 1:
Python3
import random# remember this state state = random.getstate()# print 10 random numbersprint(random.sample(range(20), k = 10)) # restore staterandom.setstate(state)# print same first 5 random numbers# as aboveprint(random.sample(range(20), k = 5)) |
Output:
[16, 1, 0, 11, 19, 3, 7, 5, 10, 13] [16, 1, 0, 11, 19]
Example 2:
Python3
import random list1 = [1, 2, 3, 4, 5, 6] # Get the statestate = random.getstate()# prints a random value from the listprint(random.choice(list1)) # Set the staterandom.setstate(state)# prints the same random value# from the listprint(random.choice(list1)) |
Output:
3 3
