以递归方式获取文件夹和子文件夹下的所有文件，没有子文件夹本身的路径

Question

我想递归列出文件夹及其所有子文件夹下的所有文件的完整路径。有办法吗？好像文件分2层的话，代码可以这样写，

import os


folderPATH = r'C:\Users\Arman\Desktop\Cosmology\Articles'
filePATHS = [x[2] for x in os.walk(folderPATH)]

for i in filePATHS:
    for j in i:
        print(j)

我想要一个产生相同结果的函数但具有递归逻辑和完整路径。这样对于 n 嵌套文件夹，我可以找到路径。我需要这样的东西，

import os

def get_all_filePATHs(folderPATH):
    ...
    return get_all_filePATHs()

folderPATH = r'C:\Users\Arman\Desktop\Cosmology\Articles'
print(get_all_filePATHs(folderPATH))

请注意，我只对 文件的完整路径感兴趣，而不是子文件夹的路径 ，正如您从上面的示例中看到的那样。

Answer 1

os.walk() 递归到所有子目录。每次迭代返回的第一个元素是目录的路径，您将其与文件名连接以获得文件的完整路径。

def get_all_filePaths(folderPath):
    result = []
    for dirpath, dirnames, filenames in os.walk(folderPath):
        result.extend([os.path.join(dirpath, filename) for filename in filenames])
    return result

Answer 2

使用Pathlib

from pathlib import Path
# set main directory
folderPATH=Path('Оплата')
# loop over subdirs and files
print([Path(folderPATH.resolve().parent, the_path) for the_path in folderPATH.rglob("*")])

以递归方式获取文件夹和子文件夹下的所有文件，没有子文件夹本身的路径
