Python random  : setstate()


This article demonstrate how to use random.setstate()  method.The setstate() method of the random module is used in conjugation with the getstate() method. After using the getstate() method to capture the state of the random number generator, the setstate() method is used to restore the state of the random number generator back to the specified state.

The setstate() method requires a state object as a parameter which can be obtained by invoking the getstate() method.


Syntax:

random.setstate(state)


Parameter Values :

ParameterDescription
stateIt is required to restore the state of the random number generator.



Here are some examples of Python Random setstate() Method :

1.

          #importing random module
import random

#print a random number
print("Random number : ",random.random())

# capture the current state 
# using the getstate() method 
state = random.getstate()

#print another random number
print("Random number after capturing the state : ",random.random())

# restore the captured state 
# using the setstate() method 
# pass the captured state as the parameter
random.setstate(state)

#And the next random number should be the same as when you captured the state:
print("Random number after using the captured state : ",random.random()) 

Output :

Random number :  0.10854627972820341
Random number after capturing the state :  0.5273642326880895
Random number after using the captured state :  0.5273642326880895 


2.

 # import the random module 
import random 
   
l = [12345678910]   
  
# capture the current state 
# using the getstate() method 
state = random.getstate() 
  
# Prints list of random items of given length  
print(random.sample(l, 6))  
  
# restore the captured state 
# using the setstate() method 
# pass the captured state as the parameter 
random.setstate(state) 
  
# now printing the same list of random 
# items 
print(random.sample(l, 6))

Output :

[1065813]
[1065813
