Random模块用于在Python中生成随机数。实际上不是随机的，而是用于生成伪随机数的。这意味着可以确定这些随机生成的数字。
setstate()
的setstate()的方法random模块与getstate()方法。使用后getstate()捕获随机数生成器状态的方法setstate()方法用于将随机数生成器的状态恢复到指定状态。
的setstate()方法需要状态对象作为参数，可以通过调用getstate()方法。
范例1：
# import the random module
import random
# capture the current state
# using the getstate() method
state = random.getstate()
# print a random number of the
# captured state
num = random.random()
print("A random number of the captured state:"+ str(num))
# print another random number
num = random.random()
print("Another random number:"+ str(num))
# restore the captured state
# using the setstate() method
# pass the captured state as the parameter
random.setstate(state)
# now printing the same random number
# as in the captured state
num = random.random()
print("The random number of the previously captured state:"+ str(num))输出：
A random number of the captured state:0.8059083574308233
Another random number:0.46568313950438245
The random number of the previously captured state:0.8059083574308233
范例2：
# import the random module
import random
list1 = [1, 2, 3, 4, 5]
# capture the current state
# using the getstate() method
state = random.getstate()
# Prints list of random items of given length
print(random.sample(list1, 3))
# 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(list1, 3)) 输出：
[5, 2, 4] [5, 2, 4]
