random.getstate() in Python (original) (raw)

Last Updated : 27 Jul, 2021

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 numbers

print(random.sample(range(20), k = 10))

restore state

random.setstate(state)

print same first 5 random numbers

as above

print(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 state

state = random.getstate()

prints a random value from the list

print(random.choice(list1))

Set the state

random.setstate(state)

prints the same random value

from the list

print(random.choice(list1))
