使用发电机

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)

def list_files(path):
    # returns a list of names (with extension, without full path) of all files 
    # in folder path
    files = []
    for name in os.listdir(path):
        if os.path.isfile(os.path.join(path, name)):
            files.append(name)
    return files 

仅获取文件列表（无子目录）的单行解决方案：

filenames = next(os.walk(path))[2]

或绝对路径名：

paths = [os.path.join(path, fn) for fn in next(os.walk(path))[2]]

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))]

如果您正在寻找find的Python实现，这是我经常使用的方法：

from findtools.find_files import (find_files, Match)

# Recursively find all *.sh files in **/usr/bin**
sh_files_pattern = Match(filetype='f', name='*.sh')
found_files = find_files(path='/usr/bin', match=sh_files_pattern)

for found_file in found_files:
    print found_file

所以我用它制作了一个PyPI包，还有一个GitHub存储库。我希望有人发现它对这段代码可能有用。

我更喜欢使用glob模块，因为它可以进行模式匹配和扩展。

import glob
print(glob.glob("/home/adam/*"))

它可以直观地进行模式匹配

import glob
# All files and directories ending with .txt and that don't begin with a dot:
print(glob.glob("/home/adam/*.txt")) 
# All files and directories ending with .txt with depth of 2 folders, ignoring names beginning with a dot:
print(glob.glob("/home/adam/*/*.txt")) 

它将返回一个包含查询文件和目录的列表：

['/home/adam/file1.txt', '/home/adam/file2.txt', .... ]

注意，glob忽略以点开头的文件和目录。，因为这些被认为是隐藏的文件和目录，除非模式类似于.*。

使用glob.escape转义不应该是模式的字符串：

print(glob.glob(glob.escape(directory_name) + "/*.txt"))
