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()  if s == '1':    print([x ** 3 for x in range(10)])elif s == '2':    print([x ** 3 for x in [0, 2, 4, 6, 8]])elif s == '3':    print([(x, x ** 3) for x in [1, 3, 5, 7, 9]])elif s == '4':    for i in range(4):        ls[i] = ls[i].capitalize()    print(ls)else:    print('结束程序')

第3关：列表的合并与排序

list1 = list(map(int,input().split()))list2 = list(map(int,input().split()))for i in list2:    list1.append(i)list1.sort(reverse=True)print(list1)

第4关：二维列表排序

第5关：动物重量排序

ls = []while True:    temp = input()     if temp == '':         break    ls.append(temp.split()) print(sorted(ls,key=lambda x:float(x[1][:-1]) * 1000 if x[1][-1] == 't' else float(x[1][:-2])))
