想要在整数和浮点数之间排序，整数从最低到最高排序

Question

我有一个包含以下数据的文件：1,0.000081181,0.0000810112,0.000081225,0.000080918,0.000080921,0.000081092,0.00008100260,0.00008087248,0.0000798269,0.0000795871,0.0000795451,0.0000791020,0.00007932我希望能够对文件进行排序，以便将整数值从最低到最高排序。使用 sorted 函数进行排序时，它似乎是按数字排序。a_s = sorted(List)for i in a_s:    print(i)所以输出是：1,0.000081011,0.000081091,0.0000811812,0.000081222,0.0000810020,0.00007932248,0.00007982260,0.000080875,0.0000809151,0.0000791069,0.0000795871,0.000079548,0.00008092我将如何获得它以便将数值从最低值到最高值排序？

Answer 1

尝试这个：

with open('test.txt') as fp:

    data = [line.strip().split(',') for line in fp]

res = '\n'.join([','.join(x) for x in sorted(data, key=lambda x: int(x[0]))])

print(res)

输出：

1,0.00008118

1,0.00008101

1,0.00008109

2,0.00008100

5,0.00008091

8,0.00008092

12,0.00008122

20,0.00007932

51,0.00007910

69,0.00007958

71,0.00007954

248,0.00007982

260,0.00008087
