import random
    
    player = input('请输入(0)剪刀 (1)石头 (2)布')
    
    
    
    print('用户输入的是',player)
    
    computer  = random.choice(['剪刀','石头','布'])
    print('computer输入的是',computer)
    if (player == '剪刀' and computer == '布') or (player =='石头' and  computer == '剪刀') or( player =='布'and computer =='石头'):
        print('player is the winner')
    elif (computer == '剪刀' and player == '布' )or  (computer=='石头' and  player == '剪刀') or (computer =='布'and player =='石头'):
        print('computer is the winner')
    elif (computer == '剪刀' and player == '剪刀' )or  (computer=='石头' and  player == '石头') or (computer =='布'and player =='布'):
        print('tie')
    else:
        print('please input 剪刀or 石头 or布')

random函数使用举例

import random
    a=random.uniform(0,10)#产生0到10之间随机浮点数
    b=int(a)
    print(a,b)
    #3.8304270476116855 3
    
    c=random.random()#产生0到1之间浮点随机数
    print(c)
    #0.8111126969399767
    
    d=random.randint(1,10)#产生 [1,10] 1到10之间整数型随机数(包括1和10)
    print(d)
    #6
    
    e=random.choice('tomorrow')   # 从序列中随机选取一个元素
    print(e)
    
    
    print( random.randrange(1,10,2) )
    # 生成从 [1,10) 1到10的间隔为2的随机整数，如1，3，5，7，9
    
    a=[1,3,5,6,7]                # 将序列a中的元素顺序打乱
    random.shuffle(a)
    print(a)
    
    
    # 多个字符中生成指定数量的随机字符：
    print (random.sample('zyxwvutsrqponmlkjihgfedcba',5))
    
    
    
    # 多个字符中选取指定数量的字符组成新字符串：
    print (''.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)))
    
    # 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))
