import os
def get_files(search_path):
     for (dirpath, _, filenames) in os.walk(search_path):
         for filename in filenames:
             yield os.path.join(dirpath, filename)
list_files = get_files('.')
for filename in list_files:
    print(filename)

我将提供一个示例单行，其中可以提供源路径和文件类型作为输入。代码返回带有csv扩展名的文件名列表。使用以防需要返回所有文件。这还将递归扫描子目录。

[y代表os.walk中的x（sourcePath）代表glob中的y（os.path.join（x[0]，'*.csv'））]

根据需要修改文件扩展名和源路径。

返回绝对文件路径列表，不会递归到子目录

L = [os.path.join(os.getcwd(),f) for f in os.listdir('.') if os.path.isfile(os.path.join(os.getcwd(),f))]

Python 3.4+的另一个非常可读的变体是使用pathlib.Path.glob：

from pathlib import Path
folder = '/foo'
[f for f in Path(folder).glob('*') if f.is_file()]

更具体一些很简单，例如，只在所有子目录中查找非符号链接的Python源文件：

[f for f in Path(folder).glob('**/*.py') if not f.is_symlink()]

从目录及其所有子目录获取完整文件路径

import os

def get_filepaths(directory):
    """
    This function will generate the file names in a directory 
    tree by walking the tree either top-down or bottom-up. For each 
    directory in the tree rooted at directory top (including top itself), 
    it yields a 3-tuple (dirpath, dirnames, filenames).
    """
    file_paths = []  # List which will store all of the full filepaths.

    # Walk the tree.
    for root, directories, files in os.walk(directory):
        for filename in files:
            # Join the two strings in order to form the full filepath.
            filepath = os.path.join(root, filename)
            file_paths.append(filepath)  # Add it to the list.

    return file_paths  # Self-explanatory.

# Run the above function and store its results in a variable.   
full_file_paths = get_filepaths("/Users/johnny/Desktop/TEST")

我在上述函数中提供的路径包含3个文件，其中两个位于根目录中，另一个位于名为“subfolder”的子文件夹中打印将打印列表的完整文件路径：['/Users/johnny/Desktop/TEST/file1.txt'，'/Users/johnny/Desctop/TEST-file2.txt'，'/Users/johnny/Desktop/STEST/SUBFOLDER/file3.dat']

如果愿意，您可以打开并阅读内容，或者只关注扩展名为“.dat”的文件，如下面的代码所示：

for f in full_file_paths:
  if f.endswith(".dat"):
    print f

/用户/johnny/Desktop/TEST/SUBFOLDER/file3.dat
