如何将毫秒转换为天/小时/分钟

def convert_milliseconds_to_time(milliseconds):
    # 定义时间单位的转换常量
    SECONDS_IN_MINUTE = 60
    MINUTES_IN_HOUR = 60
    HOURS_IN_DAY = 24
    
    # 将毫秒转换为秒
    seconds = milliseconds / 1000
    
    # 将秒转换为分钟
    minutes = seconds / SECONDS_IN_MINUTE
    
    # 将分钟转换为小时
    hours = minutes / MINUTES_IN_HOUR
    
    # 将小时转换为天
    days = hours / HOURS_IN_DAY
    
    # 计算整数部分和小数部分
    days_int = int(days)
    remaining_hours = (days - days_int) * HOURS_IN_DAY
    hours_int = int(remaining_hours)
    remaining_minutes = (remaining_hours - hours_int) * MINUTES_IN_HOUR
    minutes_int = int(remaining_minutes)
    remaining_seconds = (remaining_minutes - minutes_int) * SECONDS_IN_MINUTE
    seconds_int = int(round(remaining_seconds))
    
    return days_int, hours_int, minutes_int, seconds_int

# 示例使用
milliseconds = 987654321
days, hours, minutes, seconds = convert_milliseconds_to_time(milliseconds)
print(f"{milliseconds} 毫秒等于 {days} 天 {hours} 小时 {minutes} 分钟 {seconds} 秒")

def convert_milliseconds_to_time(milliseconds):
    if milliseconds < 0:
        raise ValueError("毫秒数不能为负数")
    # 其余代码保持不变
