python 字典，列表，元組__python

基礎操作：

##########################列表#############################aList = [1,2,3,4,5]#python 中 list 是可變類型，像下面這樣修改是合法的#增aList.append(6)#刪aList.pop()#改aList[0] = 100#查print(aList[0])for v in aList:    print(v)##############元組##########################aTuple = (1,2,3,4,5)#在python 元組是不可變類型，不可修改,像下面的操作時非法的# aTuple[0] = 2#查for v in aTuple:    print(v)################字典#########################aDict = {"name":"zhengjinwei","age":23,"sex":"male"}#在python 中字典是可以修改的#增aDict["index"] = 1#刪aDict.pop("index")aDict.clear()#改aDict["name"]="bloodchilde"#查for index,k in enumerate(aDict):    print index,k,aDict[k]

進階操作，實現棧：

#python 中list 實現棧class CStack:    def __init__(self):        self.__len = 0        self.__stack = []    def __del__(self):        del self.__stack    def push(self,obj):        self.__stack.append(obj)        self.__len += 1    def pop(self):        if not self.__len:            return None        else:            self.__len -= 1            return self.__stack.pop()    def getStackLen(self):        return self.__len    def getStackData(self):        return self.__stackstack = CStack()print(stack.getStackData())print(stack.pop())stack.push(1)stack.push("zjw")print(stack.getStackData())print(stack.pop())print(stack.pop())

進階操作，實現隊列：

#python list 實現隊列class CQueue:    def __init__(self):        self.__queue = []        self.__len = 0    def __del__(self):        del self.__queue    def enter_queue(self,obj):        self.__queue.append(obj)        self.__len += 1    def del_queue(self):        if not self.__len:            return None        else:            self.__len -= 1            return self.__queue.pop(0)    def view_queue(self):        return self.__queuequeue = CQueue()print(queue.view_queue())# enter the queuequeue.enter_queue(1)queue.enter_queue(2)print(queue.view_queue())#out the queueprint(queue.del_queue())#show 1print(queue.del_queue())#show 2print(queue.del_queue()) #will show None
