python作业（面向对象）

通过面向对象的方式实现队列和栈的数据结构;

l = []
l.get()

class Stack():

s = Stack()
s.pop()
s.push()
s.info()
s.getSize()

源代码

stack=[1,2]
class Stack(object):    #栈的类
    def __init__(self):
        pass
    def pop(self):
        if len(stack) == 0:
            print "空栈"
        else:
            print stack.pop(),"元素被弹出"
    def push(self):
        item = raw_input("入栈元素:")
        stack.append(item)
        print "%s元素入栈成功" %(item)
    def info(self):
        print "当前栈内的元素为：",
        for i in stack:
        print i,
        print ""
    def getSize(self):
        print "当前栈内的元素有%d个" %(len(stack))

class Queue(object):    ##队列的类
    def __init__(self):
        pass
    def pop(self):
        if len(stack) == 0:
            print "空队列"
        else:
            print stack.pop(0),"元素被弹出"
    def push(self):
        item = raw_input("入队列元素:")
        stack.append(item)
        print "%s元素入队列成功" %(item)
    def info(self):
        print "当前队列内的元素为：",
        for i in stack:
        print i,
        print ""
    def getSize(self):
        print "当前队列内的元素有%d个" %(len(stack))

s = Stack()
s.info()
s.push()
s.info()
s.pop()
s.info()
s.getSize()

管理系统雏形

西部开源：学校，学员，讲师
   学校:
      属性:名称，地点，校训
       方法:招生，招聘讲师

   学员:
        属性:姓名， 年龄， 性别，班级，学号
         方法:学习，交钱，显示信息


 讲师
       属性:姓名， 年龄， 性别, 课程， 工资
       方法:讲课，显示信息

 学员保存在字典里，讲师保存在字典里
