.小明在吹一下午的风扇,觉得有点冷了,现在让创造师给小明的风扇慢慢降低转速吧。该 如何做呢?

为了模拟风扇逐渐降低转速的过程,你可以编写一个简单的程序,比如每隔一段时间减小转速。下面是一个使用Python字典表示风扇状态的例子:
```python
class FAN_SPEED:
SLOWEST = 0
FASTEST = 100 # 设定最大转速
def slow_fan(speed_dict, target_speed):
if target_speed > speed_dict['current_speed']:
delta = (target_speed - speed_dict['current_speed']) // 5 # 每次减小5%
speed_dict['current_speed'] -= delta
print(f"风扇转速从{speed_dict['current_speed']}%下降至{speed_dict['current_speed']}%")
if speed_dict['current_speed'] < FAN_SPEED.SLOWEST:
print("风扇已经调到最慢")
else:
print("风扇已处于最低转速")
# 初始化风扇状态
speed_dict = {'current_speed': FAN_SPEED.FASTEST}
# 开始降低转速
for _ in range(FAN_SPEED.FASTEST // 5): # 从最大转速开始,每5%步一次
slow_fan(speed_dict, FAN_SPEED.SLOWEST)
