搅拌机：rpint 版本

搅拌机是一种常见的厨房电器，用于将不同的食材搅拌或混合起来。在程序员的世界里，我们也可以用代码实现搅拌机的功能。rpint 版本的搅拌机是一款可以在控制台中运行的程序，能够通过命令行参数设置不同的参数并进行搅拌。

功能

• 将多个食材搅拌或混合
• 通过命令行参数设置搅拌时间、速度，以及搅拌方式（单向或双向）
• 支持不同类型的搅拌器头，如螺旋形、圆形、扁平形等
• 支持暂停、继续、停止等操作

代码片段

import time

class Mixer:
    def __init__(self, time_limit, speed, direction):
        self.time_limit = time_limit
        self.speed = speed
        self.direction = direction
        self.running = False
    
    def start(self, ingredients, mixer_head):
        self.running = True
        start_time = time.time()
        
        while self.running:
            elapsed_time = time.time() - start_time
            if elapsed_time >= self.time_limit:
                self.stop()
                break
            
            if self.direction == 'cw':
                mixer_head.cw_mix(ingredients)
                
            elif self.direction == 'ccw':
                mixer_head.ccw_mix(ingredients)
                
            time.sleep(1 / self.speed)
    
    def pause(self):
        self.running = False
        
    def resume(self):
        self.running = True
    
    def stop(self):
        self.running = False

class MixerHead:
    def __init__(self, head_type):
        self.head_type = head_type
    
    def cw_mix(self, ingredients):
        if self.head_type == 'spiral':
            print('Mixing with spiral head in clockwise direction')
            # TODO: perform mixing using spiral head
        elif self.head_type == 'round':
            print('Mixing with round head in clockwise direction')
            # TODO: perform mixing using round head
        elif self.head_type == 'flat':
            print('Mixing with flat head in clockwise direction')
            # TODO: perform mixing using flat head
            
    def ccw_mix(self, ingredients):
        if self.head_type == 'spiral':
            print('Mixing with spiral head in counter-clockwise direction')
            # TODO: perform mixing using spiral head
        elif self.head_type == 'round':
            print('Mixing with round head in counter-clockwise direction')
            # TODO: perform mixing using round head
        elif self.head_type == 'flat':
            print('Mixing with flat head in counter-clockwise direction')
            # TODO: perform mixing using flat head

使用方式

• 通过命令行参数设置参数
• 调用 Mixer.start() 方法开始搅拌
• 调用 Mixer.pause() 方法暂停搅拌
• 调用 Mixer.resume() 方法继续搅拌
• 调用 Mixer.stop() 方法停止搅拌

import argparse

parser = argparse.ArgumentParser(description='rpint version mixer')

parser.add_argument('--time_limit', type=float, default=60, help='the time limit for mixing in seconds')
parser.add_argument('--speed', type=float, default=1, help='the speed of mixing')
parser.add_argument('--direction', type=str, default='cw', help='the direction of mixing (cw or ccw)')
parser.add_argument('--head_type', type=str, default='spiral', help='the type of mixer head (spiral, round, flat)')

args = parser.parse_args()

mixer_head = MixerHead(args.head_type)
mixer = Mixer(args.time_limit, args.speed, args.direction)
mixer.start(ingredients, mixer_head)

# to pause mixing
mixer.pause()

# to resume mixing
mixer.resume()

# to stop mixing
mixer.stop()

总结

rpint 版本的搅拌机是一款高效、灵活的程序，可以通过简单的命令行参数设置实现不同的搅拌效果。程序员们可以在厨房外也能体验到搅拌的乐趣。
