什么是Python中的顺序表

# 创建顺序表class Sequence_Table(): 
 # 初始化
 def __init__(self):
 self.date = [None]*100

 # 判断是否已经满了
 def isFull(self): 
 if self.length>100: 
 print("该顺序表已满，无法添加元素") 
 return 1

 return 0 
 # 按下表索引查找

 if index>=0 and index<=self.length-1: 
 return self.date[index] 
 else: 
 print("你输入的下标不对，请重新输入\n")

 # 按元素查下标

 isContain = 0 
 for i in range(0,self.length): 
 if self.date[i] == num:
 isContain = 1 
 print("你要查找的元素下标是%d\n"%i) 
 if isContain == 0: 
 print("没有找你你要的数据") 
 # 追加数据
 def addNum(self,num): 
 if self.isFull() == 0:
 self.date[self.length] = num
 self.length += 1 
 # 打印顺序表
 def printAllNum(self):

 print("a[%s]=%s"%(i,self.date[i]),end=" ") 
 print("\n")

// 1、定义顺序表的储存结构
typedef struct

 //用数组存储线性表中的元素
 int data[100];
 // 顺序表中的元素个数
 int length;

// 2、顺序表的初始化，
void initSequenceTable(p_Sequence_table T)
