线性表删除元素

在线性表中删除指定元素：

 1 class deleelem_in_linelist():
 2     def __init__(self,list,maxsize):
 3         self.data = list
 4         self.length = len(list)
 5         self.maxsize = maxsize
 6     def dele_elem_in_list(self,e):
 7         for i in self.data:
 8             if i == e:
 9                 self.data.remove(i)
10                 print("删除元素%s成功"%e)
11             # else:
12             #     print("线性表中不存在元素%s"%e)
13         return self.data
14 
15 if __name__ == '__main__':
16     ob = deleelem_in_linelist([1, 2, 3, 7, 8, 9, 10, 11, 12, 13, 14], 20)
17     print(ob.data)
18     ob.dele_elem_in_list(15)
19     print(ob.data)
20     ob.dele_elem_in_list(10)
21     print(ob.data)

在线性表指定位置删除元素：
