Python 3 - Number seed() Method

---

Description

The seed() method initializes the basic random number generator. Call this function before calling any other random module function.

Syntax

Following is the syntax for seed() method:

seed ([x], [y])

Note − This function initializes the basic random number generator.

Parameters

x − This is the seed for the next random number. If omitted, then it takes system time to generate the next random number. If x is an int, it is used directly.

y − This is version number (default is 2). str, byte or byte array object gets converted in int. Version 1 used hash() of x.

Return Value

This method does not return any value.

Example

The following example shows the usage of seed() method.

#!/usr/bin/python3
import random

random.seed()
print ("random number with default seed", random.random())

random.seed(10)
print ("random number with int seed", random.random())

random.seed("hello",2)
print ("random number with string seed", random.random())

Output

When we run above program, it produces the following result −

random number with default seed 0.2524977842762465
random number with int seed 0.5714025946899135
random number with string seed 0.3537754404730722
