Python：每日一题 89（答题领鱼币）

冬雪雪冬

有一个由数字组成的列表：

1. [1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, 484, 529, 576, 625, 676, 729, 784, 841, 900, 961, 1024, 1089, 1156, 1225, 1296, 1369, 1444, 1521, 1600, 1681, 1764, 1849, 1936, 2025, 2116, 2209, 2304, 2401, 2500, 2601, 2704, 2809, 2916, 3025, 3136, 3249, 3364, 3481, 3600, 3721, 3844, 3969, 4096, 4225, 4356, 4489, 4624, 4761, 4900, 5041, 5184, 5329, 5476, 5625, 5776, 5929, 6084, 6241, 6400, 6561, 6724, 6889, 7056, 7225, 7396, 7569, 7744, 7921, 8100, 8281, 8464, 8649, 8836, 9025, 9216, 9409, 9604, 9801]

复制代码

现在要把他们排序，要求按各位数字之和的大小，由小到大排序。结果为

1. [1, 100, 4, 121, 400, 16, 25, 1024, 1600, 2401, 2500, 9, 36, 81, 144, 225, 324, 441, 900, 1521, 2025, 2304, 2601, 3600, 8100, 64, 361, 1225, 2116, 3025, 5041, 6400, 49, 256, 625, 841, 1156, 1444, 2209, 2704, 3136, 3721, 4225, 4900, 6241, 169, 196, 484, 529, 961, 1681, 3364, 3481, 4624, 7225, 9025, 576, 729, 1089, 1296, 1764, 2916, 3249, 4356, 4761, 5184, 5625, 6084, 6561, 7056, 9216, 9801, 289, 676, 784, 1369, 1936, 2809, 3844, 4096, 5329, 6724, 7921, 8281, 9604, 1849, 5476, 7744, 8464, 9409, 4489, 5776, 5929, 7396, 8836, 3969, 7569, 8649, 6889]

折腾sorted函数咯

2.     return sorted(a, key=lambda x: sum(int(i) for i in str(x)))

大神们的代码一眼看不懂，来个笨一点的

1. list0 = [i*i for i in range(1,100)]
   
2. list1 = []
   
3. for i in list0:
   
4.     sum = 0
   
5.     for j in str(i):
   
6.         sum+=int(j)
   
7.     list1.append(sum)
   
8. dict0=dict(zip(list0,list1))
   
9. dict1=dict(sorted(dict0.items(),key=lambda item:item[1]))
   
10. print(list(dict1.keys()))

我刚学，我觉得把数组中第一第二个进行比较，再第二第三个进行比较。。。如此换位就成功啦
