Learn Python 016: Coin - a project of msc, unfinished.-优快云博客

本文介绍了一个使用Python实现的硬币类设计，包括基本属性设置、稀有度判断、清洁与氧化处理方法及抛掷硬币等功能。通过继承实现了英镑硬币的具体类。

import random

class Coin:

    def __init__(self, rare=False, clean=True, **kwargs):

        for key,value in kwargs.items():
            setattr(self,key,value)

        else:
            self.value = self.original_value * 1.0

        self.heads = choice

    def __del__(self):
        print('Coin spent!')
