python头歌-python第六章作业

第1关 列表的属性与方法

def main(n):    ls = []    for i in range(n):        lsinput = input().split()        operate = lsinput[0]        if operate == 'insert':            ls.insert(int(lsinput[1]),int(lsinput[2]))        elif operate == 'remove':            ls.remove(int(lsinput[1]))        elif operate == 'append':            ls.append(int(lsinput[1]))        elif operate == 'sort':            ls.sort()        elif operate == 'pop':            ls.pop()            elif operate == 'reverse':            ls.reverse()        elif operate == 'print':            print(ls)if __name__ == '__main__':    N = int(input())    main(N)

第2关 推导式与生成器

ls = ['the lord of the rings','anaconda','legally blonde','gone with the wind']s = input()        # 输入一个字符# 当输入为"1"时，输出元素为0-9的3次方的列表 [0, 1, 8, 27, 64, 125, 216, 343, 512, 729]if s == '1':
