使用python做一个简单的互动功能（学习）

import random

gold = 0
while True:
    print('现在拥有的%d' % gold)
    if gold >= 5:
        print('_________准备开始游戏___________')
        gold -= 5
        dice1 = random.randint(1, 6)
        dice2 = random.randint(1, 6)
        dice3 = dice1 + dice2
        guess = input('请输入大/小')
        if dice3 < 6 and guess == '小' or dice3 >= 6 and guess == '大':
            print('你赢了')
            gold += 2
            print('当前拥有的金币为%d,' % gold)
            goon = input('还继续吗？y/n')
            if goon == 'n':
                break
        else:
