import randomimport string#随机整数：print random.randint(1,50)#随机选取0到100间的偶数：print random.randrange(0, 101, 2)#随机浮点数：print random.random()print random.uniform(1, 10)#随机字符：print random.choice('abcdefghijklmnopqrstuvwxyz!@#$%^&*()')#多个字符中选取特定数量的字符：print random.sample('zyxwvutsrqponmlkjihgfedcba',5)#多个字符中选取特定数量的字符组成新字符串：print string.join(random.sample(['z','y','x','w','v','u','t','s','r','q','p','o','n','m','l','k','j','i','h','g','f','e','d','c','b','a'], 5)).replace(' ','')#随机选取字符串：print random.choice(['剪刀', '石头', '布'])#打乱排序items = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]print random.shuffle(items)
