list 是一种元素个数可变的线性表,采用了分离式技术实现的动态顺序表。可以加入和删除元素,并在各种操作中维持已有元素的顺序(即保序)。
# 创建顺序表
def CreateSeqList(self):
element = input("please enter(input #:end):")
while element != '#':
self.seqList.append(int(element))
element = input("please enter(input #:end):")
# 查找顺序表中某一个元素
def FindElement(self):
key = int(input("please enter what you want to find:"))
if key in self.seqList:
keyPosition = self.seqList.index(key)
result = keyPosition
else:
result = "none"
return result
# 在指定位置上插入元素
def InsertElement(self):
postion = int(input("请输入要插入的位置:"))
key = int(input("请输入要插入的值:"))
print("插入前顺序:", self.seqList)
self.seqList.insert(postion, key)
print("插入后顺序:", self.seqList)
# 在指定位置上删除元素
def DeleteElement(self):
postion = int(input("请输入要删除元素的位置:"))
print("删除前的顺序表:", self.seqList)
if postion < len(self.seqList) and postion >= 0:
del self.seqList[postion]
return self.seqList
else:
print("不存在啊老铁,删除个毛线啊")
class SequenceList: # 初始化 def __init__(self): self.seqList = [] # 初始化一个空表 # 创建顺序表 def CreateSeqList(self): element = input("please enter(input #:end):") while element != '#': self.seqList.append(int(element)) element = input("please enter(input #:end):") # 查找顺序表中某一个元素 def FindElement(self): key = int(input("please enter what you want to find:")) if key in self.seqList: keyPosition = self.seqList.index(key) result = keyPosition else: result = "none" return result # 在指定位置上插入元素 def InsertElement(self): postion = int(input("请输入要插入的位置:")) key = int(input("请输入要插入的值:")) print("插入前顺序:", self.seqList) self.seqList.insert(postion, key) print("插入后顺序:", self.seqList) # 在指定位置上删除元素 def DeleteElement(self): postion = int(input("请输入要删除元素的位置:")) print("删除前的顺序表:", self.seqList) if postion < len(self.seqList) and postion >= 0: del self.seqList[postion] return self.seqList else: print("不存在啊老铁,删除个毛线啊") # 遍历顺序表元素 def TraverseElement(self): for i in range(len(self.seqList)): print(self.seqList[i], end =' ') # 判空 def IsEmpty(self): return len(self.seqList) == 0 # 销毁顺序表 def DestorySeqList(self): print("销毁前顺序表:", self.seqList) self.__init__() print("销毁后顺序表:", self.seqList) # 测试 if __name__ == '__main__': list = SequenceList() list.CreateSeqList() print(list.seqList) print(list.FindElement()) list.InsertElement() list.DeleteElement() list.TraverseElement() list.IsEmpty() list.DestorySeqList()
