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':
