Question

所以我有一个包含姓名，分数和班级的文本文件 e.g。

= ('test', ' in class', '1', ' has got a score of', 1)

我如何对它进行排序（文本文件），以便按分数对其进行数字排序？

Answer 1

首先，将文件读入列表列表：

with open(filepath, 'r') as file:
    list = []
    for line in file:
        list.append(line[1:-1].split(","))

现在你有这样的事情：

list == [['test', ' in class', '1', ' has got a score of', 3],
         ['test', ' in class', '1', ' has got a score of', 5],
         ['test', ' in class', '1', ' has got a score of', 1],
         ['test', ' in class', '1', ' has got a score of', 2]]

然后对列表中的列表进行排序：

list.sort(key=lambda x: int(x[4]))

这导致这个排序列表：

list = [['test', ' in class', '1', ' has got a score of', 1],
        ['test', ' in class', '1', ' has got a score of', 2],
        ['test', ' in class', '1', ' has got a score of', 3],
        ['test', ' in class', '1', ' has got a score of', 5]]

Answer 2

您可以将sorted()功能用作

sorted_lines = sorted(lines, key = lambda x : x[4] )

示例

>>> lines = [ ('test', ' in class', '1', ' has got a score of', 1), ('test', ' in class', '4', ' has got a score of', 4), ('test', ' in class', '5', ' has got a score of', 5), ('test', ' in class', '3', ' has got a score of', 3), ('test', ' in class', '2', ' has got a score of', 2) ] >>> sorted_lines = sorted(lines, key = lambda x : x[4] ) >>> soted_lines ('test', ' in class', '1', ' has got a score of', 1) ('test', ' in class', '2', ' has got a score of', 2) ('test', ' in class', '3', ' has got a score of', 3) ('test', ' in class', '4', ' has got a score of', 4) ('test', ' in class', '5', ' has got a score of', 5)
