在“path/to/images”中扩展名为“jpg”和“png”的文件名:

import os
accepted_extensions = ["jpg", "png"]
filenames = [fn for fn in os.listdir("path/to/images") if fn.split(".")[-1] in accepted_extensions]

过滤器与glob模块:

Import glob

import glob

通配符:

files=glob.glob("data/*")
print(files)

Out:

['data/ks_10000_0', 'data/ks_1000_0', 'data/ks_100_0', 'data/ks_100_1',
'data/ks_100_2', 'data/ks_106_0', 'data/ks_19_0', 'data/ks_200_0', 'data/ks_200_1', 
'data/ks_300_0', 'data/ks_30_0', 'data/ks_400_0', 'data/ks_40_0', 'data/ks_45_0', 
'data/ks_4_0', 'data/ks_500_0', 'data/ks_50_0', 'data/ks_50_1', 'data/ks_60_0', 
'data/ks_82_0', 'data/ks_lecture_dp_1', 'data/ks_lecture_dp_2']

Fiter扩展名。txt:

files = glob.glob("/home/ach/*/*.txt")

单个字符

glob.glob("/home/ach/file?.txt")

数量范围

glob.glob("/home/ach/*[0-9]*")

字母范围

glob.glob("/home/ach/[a-c]*")

使用操作系统。遍历递归列出您的文件

import os
root = "/home"
pattern = "145992"
alist_filter = ['jpg','bmp','png','gif'] 
path=os.path.join(root,"mydir_to_scan")
for r,d,f in os.walk(path):
    for file in f:
        if file[-3:] in alist_filter and pattern in file:
            print os.path.join(root,file)

import glob

jpgFilenamesList = glob.glob('145592*.jpg')

参见python文档中的glob

初步的代码

import glob
import fnmatch
import pathlib
import os

pattern = '*.py'
path = '.'

解决方案1 -使用“glob”

# lookup in current dir
glob.glob(pattern)

In [2]: glob.glob(pattern)
Out[2]: ['wsgi.py', 'manage.py', 'tasks.py']

解决方案 2 - 使用“os” + “fnmatch”

变体2.1 -查找当前目录

# lookup in current dir
fnmatch.filter(os.listdir(path), pattern)

In [3]: fnmatch.filter(os.listdir(path), pattern)
Out[3]: ['wsgi.py', 'manage.py', 'tasks.py']

变体2.2 -查找递归

# lookup recursive
for dirpath, dirnames, filenames in os.walk(path):

    if not filenames:
        continue

    pythonic_files = fnmatch.filter(filenames, pattern)
    if pythonic_files:
        for file in pythonic_files:
            print('{}/{}'.format(dirpath, file))

结果

./wsgi.py
./manage.py
./tasks.py
./temp/temp.py
./apps/diaries/urls.py
./apps/diaries/signals.py
./apps/diaries/actions.py
./apps/diaries/querysets.py
./apps/library/tests/test_forms.py
./apps/library/migrations/0001_initial.py
./apps/polls/views.py
./apps/polls/formsets.py
./apps/polls/reports.py
./apps/polls/admin.py

解决方案3 -使用“pathlib”

# lookup in current dir
path_ = pathlib.Path('.')
tuple(path_.glob(pattern))

# lookup recursive
tuple(path_.rglob(pattern))

注:

在Python 3.4上测试 模块“pathlib”只在Python 3.4中添加 Python 3.5使用glob.glob添加了递归查找的特性 https://docs.python.org/3.5/library/glob.html glob.glob。由于我的机器安装了Python 3.4，所以我还没有对此进行测试。

你可以使用subprocess. check_output()作为

import subprocess

list_files = subprocess.check_output("ls 145992*.jpg", shell=True) 

当然，引号之间的字符串可以是您希望在shell中执行并存储输出的任何内容。
