随机产生数值（Python）

 1 from random import randint  
 2 from random import random
 3 from random import uniform
 4 from random import choice
 5 from random import randrange
 6 from random import shuffle
 7 
 8 # 产生10个[-10, 10]的int数值
 9 # data = [randint(-10, 10) for i in range(10)]
10 
11 # 产生10个[0, 1]的float数值
12 # 保留两位小数
13 # data = [round(random(),2) for i in range(10)]
14 
15 # 产生10个[1.1, 3.3]的float数值 
16 # 边界可不是整数
17 # data = [round(uniform(1.1, 3.3), 2) for i in range(10)]
18 
19 # 从序列中随机生成2个元素
20 # data = [choice('tomorrow') for i in range(2)]
21 
22 # 随机生成1到100间隔为2的元素,顺序打乱
23 # data = [randrange(1, 100, 2) for i in range(10)]
24 
25 # 将序列元素顺序打乱
26 a = [1,2,3,4]
27 shuffle(a)
28 print(a)
