定义一个学生类，有下面的属性
姓名年龄成绩（语文，数学，英语）每课成绩类型为整数类方法
获取学生的姓名：get_name() 返回类型：str获取学生的年纪：get_age() 返回类型：int返回3门科目中最高的分数，get_course() 返回类型：int
class Student(object):
def __init__(self
, name
, age
, scores
):
self
.name
= name
self
.age
= age
self
.scores
= scores
def get_name(self
):
return self
.name
def get_age(self
):
return self
.age
def get_course(self
):
return max(self
.scores
)
zz
= Student
("aa", 18, [80, 100, 90])
print(zz
.get_name
())
print(zz
.get_age
())
print(zz
.get_course
())
aa
18
100
定义一个字典类：DictClass，完成如下功能
删除某个key del_dict(key)判断某个键是否在字典里，如果在，返回键对应的值，不在，则返回’not found’ get_dict()返回键组成的列表 返回类型：list get_key()合并字典，并且返回合并后字典的values组成的列表，返回类型 list updata_dict()
class DictClass(object):
def __init__(self
, dict):
self
.dict = dict
def del_dict(self
, key
):
if key
not in self
.dict.keys
():
return "key不在字典里"
else:
self
.dict.pop
(key
)
return "删除成功"
def get_dict(self
, key
):
if key
not in self
.dict.keys
():
return "not found"
else:
return self
.dict[key
]
def get_key(self
):
return self
.dict.keys
()
def updata_dict(self
, dict2
):
self
.dict = dict(self
.dict, **dict2
)
return self
.dict.values
()
d
= DictClass
({"a":1, "b":2})
print(d
.get_key
())
print(d
.updata_dict
({"c":3}))
print(d
.del_dict
("a"))
print(d
.get_dict
("b"))
dict_keys(['a', 'b'])
dict_values([1, 2, 3])
删除成功
2
定义一个列表的操作类 ListInfo
列表元素添加：add_key() 添加的必须数字或者字符串列表元素取值：get_key()列表合并：updata_list(list)删除并且返回最后一个元素：del_key()
class ListInfo(object):
def __init__(self
, list_val
):
self
.list = list_val
def add_key(self
, key_name
):
if isinstance(key_name
, (str, int)):
self
.list.append
(key_name
)
print(self
.list)
return "OK"
else:
return "我要字符串或者数字"
def get_key(self
, index
):
if index
>= 0 and index
< len(self
.list):
return self
.list[index
]
return "你输入的太多了！"
def updata_list(self
, new_list
):
self
.list.extend
(new_list
)
return self
.list
def del_key(self
):
if len(self
.list) >= 0:
return self
.list.pop
(-1)
else:
return "列表是空的"
list_info
= ListInfo
([1, 2, 3, 4, 5])
print(list_info
.add_key
([1,2]))
print(list_info
.get_key
(999))
print(list_info
.get_key
(3))
print(list_info
.updata_list
([8, 9, 10]))
print(list_info
.del_key
())
我要字符串或者数字
你输入的太多了！
4
[1, 2, 3, 4, 5, 8, 9, 10]
10
定义一个集合的操作类
集合元素添加：add_setinfo()集合的交集：get_intersection()集合的并集：get_union集合的差集：del_difference()
class SetInfo(object):
def __init__(self
, my_set
):
self
.sett
= my_set
def add_setinfo(self
, keyname
):
self
.sett
.add
(keyname
)
return self
.sett
def get_intersection(self
, unioninfo
):
if isinstance(unioninfo
, set):
return self
.sett
& unioninfo
else:
return "你传入的不是set"
def get_union(self
, unioninfo
):
if isinstance(unioninfo
, set):
return self
.sett
| unioninfo
return "你传入的不是set"
def del_difference(self
, unioninfo
):
if isinstance(unioninfo
, set):
return self
.sett
- unioninfo
return "你传入的不是set"
A
= set([1, 2, 3, 4, 5])
B
= set([5, 6, 3, 8])
my_set
= SetInfo
(A
)
print(my_set
.add_setinfo
(6))
print(my_set
.get_intersection
(B
))
print(my_set
.get_union
(B
))
print(my_set
.del_difference
(B
))
print(my_set
.get_union
("123"))
{1, 2, 3, 4, 5, 6}
{3, 5, 6}
{1, 2, 3, 4, 5, 6, 8}
{1, 2, 4}
你传入的不是set
