Python中如何实现轮盘赌模拟程序的投注颜色取反切换功能

核心优化点 #

• 定义颜色反向映射字典，调用即可直接切换颜色，无需单独写if bet_color == 'red'类的判断语句
• 下注颜色、当前下注额变量移出循环，保留每轮的状态记录，实现加倍+换色逻辑
• 押中后重置下注额为初始值，同时切换下注颜色；未押中时不切换颜色，下注额翻倍

import random

start_money = 100
coef = 0.001
base_bet = start_money * coef  # 初始下注额，押中后重置回该值
win = 0
loss = 0
money = start_money
colors = ["red"]*18 + ["black"]*18 + ["zero"]  # 简化原列表写法，效果完全一致
opposite_color = {"red": "black", "black": "red"}  # 颜色反向映射字典，无冗余判断的核心

# 初始化首次下注颜色、当前下注额
bet_color = random.choice(["red", "black"])
current_bet = base_bet

while money > 0:
    # 下注额不能超过剩余本金
    if current_bet > money:
        current_bet = money
    money -= current_bet
    result = random.choice(colors)
    
    if result == bet_color:
        # 押中：翻倍返奖，赢局计数+1，重置下注额，切换下注颜色
        money += current_bet * 2
        win += 1
        current_bet = base_bet
        bet_color = opposite_color[bet_color]
    else:
        # 未押中：输局计数+1，下注额翻倍，不换颜色
        loss += 1
        current_bet *= 2

games = win + loss
