1、增删查改
>>> g=list('456123456') >>> g ['4', '5', '6', '1', '2', '3', '4', '5', '6'] >>> for i in range(len(g)): g[i]=int(g[i]) >>> g [4, 5, 6, 1, 2, 3, 4, 5, 6] >>> g.append(1) >>> g [4, 5, 6, 1, 2, 3, 4, 5, 6, 1] >>> g.pop() 1 >>> g [4, 5, 6, 1, 2, 3, 4, 5, 6] >>> g[0]=3 >>> g [3, 5, 6, 1, 2, 3, 4, 5, 6] >>> g.index(1) 3
一分个数与三分个数
>>> g.count(1) 1 >>> g.count(3) 2
查询第一个三分下标
>>> g.index(3) 0
2、英文歌的一些操作
>>> abc='''every night in my dreams i see you, i feel you, that is how i know you go on far across the distance and spaces between us you have come to show you go on near, far, wherever you are i believe that the heart does go on once more you open the door and you're here in my heart and my heart will go on and on love can touch us one time and last for a lifetime and never let go till we're one love was when i loved you one true time i hold to in my life we'll always go on near, far, wherever you are i believe that the heart does go on once more you open the door and you're here in my heart and my heart will go on and on there is some love that will not go away you're here, there's nothing i fear, and i know that my heart will go on we'll stay forever this way you are safe in my heart and my heart will go on and on''' >>> abc.lower() "every night in my dreams i see you, i feel you, that is how i know you go on far across the distance and spaces between us you have come to show you go on near, far, wherever you are i believe that the heart does go on once more you open the door and you're here in my heart and my heart will go on and on love can touch us one time and last for a lifetime and never let go till we're one love was when i loved you one true time i hold to in my life we'll always go on near, far, wherever you are i believe that the heart does go on once more you open the door and you're here in my heart and my heart will go on and on there is some love that will not go away you're here, there's nothing i fear, and i know that my heart will go on we'll stay forever this way you are safe in my heart and my heart will go on and on" >>> print(abc.count('in')) 6 >>> print(abc.replace(',',' ')) every night in my dreams i see you i feel you that is how i know you go on far across the distance and spaces between us you have come to show you go on near far wherever you are i believe that the heart does go on once more you open the door and you're here in my heart and my heart will go on and on love can touch us one time and last for a lifetime and never let go till we're one love was when i loved you one true time i hold to in my life we'll always go on near far wherever you are i believe that the heart does go on once more you open the door and you're here in my heart and my heart will go on and on there is some love that will not go away you're here there's nothing i fear and i know that my heart will go on we'll stay forever this way you are safe in my heart and my heart will go on and on
3、简要描述列表与元组的异同。
元组一旦初始化就不能改变里面的元素,而列表可以。
列表中的项目应该包括在方括号中,元组在圆括号中
你可以增删改或是搜索列表中的项目。
