Question

所以我有一个文件夹，比如D：\ Tree，它只包含子文件夹（名称可能包含空格）。这些子文件夹包含一些文件 - 它们可能包含"D:\Tree\SubfolderName\SubfolderName_One.txt"和"D:\Tree\SubfolderName\SubfolderName_Two.txt"形式的文件（换句话说，子文件夹可能包含它们，一个或两者都不包含）。我需要找到子文件夹包含这两个文件的每个出现位置，并将它们的绝对路径发送到文本文件（采用以下示例中说明的格式）。在D：\ Tree：

中考虑这三个子文件夹

D:\Tree\Grass contains Grass_One.txt and Grass_Two.txt
D:\Tree\Leaf contains Leaf_One.txt
D:\Tree\Branch contains Branch_One.txt and Branch_Two.txt

鉴于此结构和上述问题，我希望能够在myfile.txt中编写以下行：

D:\Tree\Grass\Grass_One.txt D:\Tree\Grass\Grass_Two.txt
D:\Tree\Branch\Branch_One.txt D:\Tree\Branch\Branch_Two.txt

怎么可能这样做？在此先感谢您的帮助！

注意：“file_One.txt”位于myfile.txt中的“file_Two.txt”之前非常重要

Answer 1

import os

folderPath = r'Your Folder Path'

for (dirPath, allDirNames, allFileNames) in os.walk(folderPath):
    for fileName in allFileNames: 
        if fileName.endswith("One.txt") or fileName.endswith("Two.txt") :
            print (os.path.join(dirPath, fileName)) 
            # Or do your task as writing in file as per your need

希望这会有所帮助......

这是一个递归解决方案

def findFiles(writable, current_path, ending1, ending2):
    '''
    :param writable:    file to write output to
    :param current_path: current path of recursive traversal of sub folders
    :param postfix:     the postfix which needs to match before
    :return: None
    '''

    # check if current path is a folder or not
    try:
        flist = os.listdir(current_path)
    except NotADirectoryError:
        return


    # stores files which match given endings
    ending1_files = []
    ending2_files = []


    for dirname  in flist:
        if dirname.endswith(ending1):
            ending1_files.append(dirname)
        elif dirname.endswith(ending2):
            ending2_files.append(dirname)

        findFiles(writable, current_path+ '/' + dirname, ending1, ending2)

    # see if exactly 2 files have matching the endings
    if len(ending1_files)  == 1 and len(ending2_files) == 1:
        writable.write(current_path+ '/'+ ending1_files[0] + ' ')
        writable.write(current_path + '/'+ ending2_files[0] + '\n')


findFiles(sys.stdout, 'G:/testf', 'one.txt', 'two.txt')

查找包含两个以特定字符串结尾的文件的所有子文件夹
