Example

The following shows an example of using the seed() method:

#!/usr/bin/python
# -*- coding: UTF-8 -*- 
import random
random.seed( 10 )
print "Random number with seed 10 : ", random.random()
# 生成同一个随机数
random.seed( 10 )
print "Random number with seed 10 : ", random.random()
# 生成同一个随机数
random.seed( 10 )
print "Random number with seed 10 : ", random.random()

The output result after running the above example is:

Random number with seed 10 :  0.57140259469
Random number with seed 10 :  0.57140259469
Random number with seed 10 :  0.57140259469
