如何用python编码方式编写我的代码？

Question

我用 python 写了一个原始代码，我怎样才能让它看起来更像一个 python 结构，我还没有为每个函数创建类和对象，我想返回而不是打印我怎样才能明智地分离功能并在最后返回？with open(r'features.csv', 'r') as f:checker = lambda i: bool(i and i.strip())reader = csv.reader(f)header = next(reader)folders = next(    {        header[0]: [row[0]],        'Feature Name': list(filter(checker, row[:1])),        'Child folder': list(filter(checker, row[1:]))    } for row in reader)foldersinlist = list(folders.values())lists = sum(foldersinlist, [])print(lists)有什么想法吗？

如果我们知道您要如何处理返回的数据会很有帮助，我们可以为您提供更多帮助，但这应该会让您朝着正确的方向前进。

def my_function():

    with open(r'features.csv', 'r') as f:

    checker = lambda i: bool(i and i.strip())

    reader = csv.reader(f)

    header = next(reader)

    folders = next(

        {

            header[0]: [row[0]],

            'Feature Name': list(filter(checker, row[:1])),

            'Child folder': list(filter(checker, row[1:]))

        } for row in reader

    )

    foldersinlist = list(folders.values())

    lists = sum(foldersinlist, [])

    # print(lists) #Instead of this, let's return the value:

    return lists

my_data = my_function() #we're setting my_data to the returned-value of my_function

print (my_data) #Now you can us my_data wherever you need the result of my_function
