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))

                    

Output:
