废话不多说,直接上代码。

首先,先定义一个类,命名为bag_tools

clsss bag_tools():
    pass

然后,构建初始化魔法函数__init__()初始化类变量

class bag_tools():
    def __init__(self,tools_name,tools_nums):
        pass

我们目前初始化的变量有:

tools_name: 物品名称
tools_list: 物品列表
tools_nums: 物品数量
throw_things: 丢弃物品数量
del_things: 删除物品数量
self.exchange_person_name: 交换物品主人名字
self.choose_exchange_person_name: 交换物品主人是否同意

然后将其初始化

class bag_tools():
    def __init__(self,tools_name,tools_nums):
        self.tools_name = tools_name
        self.tools_list = {}
        self.tools_nums = tools_nums
        self.throw_nums = 0
        self.del_nums = 0
        self.exchange_person_name = ''
        self.choose_exchange_person_name = None

然后构建add_things方法

    def add_things(self):
        try:
            self.tools_list[self.tools_name] = int(self.tools_nums)
        except Exception as e:
            print("You input isn't a number")
        finally:
            return self.tools_list
更改物品在列表中的数量,如果没有,则按数量添加此物品

使用try… except…的原因是防止出现Error

然后构建throw_things方法

    def throw_things(self):
        try:
            self.throw_nums = int(input())
            try:
                if self.throw_nums > self.tools_list[self.tools_name]:
                    pass
                else:
                    del self.tools_list[self.tools_name]
            except Exception as e:
                print("You input isn't a number")
        except Exception as e:
            pass

然后构建del_things方法

    def del_things(self):
        try:
            self.del_nums = int(input())
            try:
                if self.del_nums > self.tools_list[self.tools_name]:
                    pass
                else:
                    del self.tools_list[self.tools_name]
            except Exception as e:
                print("You input isn't a number")
        except Exception as e:
            pass

然后构建exchange_things方法

    def exchange_things(self,name,choose):
        self.exchange_person_name = name
        if isinstance(choose,bool):
            self.choose_exchange_person_name = choose
        else:
            print("Please choose again.")

完整代码

class bag_tools():
    def __init__(self,tools_name,tools_nums):
        self.tools_name = tools_name
        self.tools_list = {}
        self.tools_nums = tools_nums
        self.throw_nums = 0
        self.del_nums = 0
        self.exchange_person_name = ''
        self.choose_exchange_person_name = None
    def add_things(self):
        try:
            self.tools_list[self.tools_name] = int(self.tools_nums)
        except Exception as e:
            print("You input isn't a number")
        finally:
            return self.tools_list
    def get_things(self):
        pass
    def exchange_things(self,name,choose):
        self.exchange_person_name = name
        if isinstance(choose,bool):
            self.choose_exchange_person_name = choose
        else:
            print("Please choose again.")
    def throw_things(self,nums):
        try:
            self.throw_nums = int(nums)
            try:
                if self.throw_nums > self.tools_list[self.tools_name]:
                    pass
                else:
                    del self.tools_list[self.tools_name]
            except Exception as e:
                print("You input isn't a number")
        except Exception as e:
            pass
    def del_things(self,nums):
        try:
            self.del_nums = int(nums)
            try:
                if self.del_nums > self.tools_list[self.tools_name]:
                    pass
                else:
                    del self.tools_list[self.tools_name]
            except Exception as e:
                print("You input isn't a number")
        except Exception as e:
            pass
