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
