一、定义一个列表的操作类Listinfo
包括的方法
1、列表元素添加：add_key() 添加的必须是数字或者是字符串
2、列表元素取值：get_key()
3、列表合并：update_list(list)
4、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):
self.list.append(key_name)
print(self.list)
return "OK"
def get_key(self, index):
#判断传入的索引是否超出了列表
if index >= 0 and index < len(self.list):
return self.list[index]
return "你输入的太多了，想太多了"
def update_list(self, new_list):
self.list.extend(new_list)
return self.list
def del_key(self):
#首先要判断我们的列表里面还有元素
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])
def __init__(self, list_val):
self.list = list_val
def add_key(self, key_name):
self.list.append(key_name)
print(self.list)
return "OK"
def get_key(self, index):
#判断传入的索引是否超出了列表
if index >= 0 and index < len(self.list):
return self.list[index]
return "你输入的太多了，想太多了"
def update_list(self, new_list):
self.list.extend(new_list)
return self.list
def del_key(self):
#首先要判断我们的列表里面还有元素
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(6))
print(list_info.update_list([8,9,10]))
print(list_info.update_list([8,9,10]))
-------------------------------------------------------------------
定义一个集合的操作类
包括的方法
1、集合元素添加：add_setinfo()
2、集合的交集：get_intersection()
3、集合的并集：get_union()
4、集合的差集：del_difference()
-------------------------------------------------------
class SecInfo(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 __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):
return self.sett | unioninfo
def del_difference(self, unioninfo):
return self.sett - unioninfo
return self.sett | unioninfo
def del_difference(self, unioninfo):
return self.sett - unioninfo
A = set([1,2,3,4,5])
B = set([5,6,3])
#my_set = SecInfo((1,2,3,4,5))
#print(my_set.add_setinfo(6))
my_set = SecInfo(A)
print(my_set.get_intersection(B))
print(my_set.del_difference(B))
B = set([5,6,3])
#my_set = SecInfo((1,2,3,4,5))
#print(my_set.add_setinfo(6))
my_set = SecInfo(A)
print(my_set.get_intersection(B))
print(my_set.del_difference(B))
