我如何在Python中获得给定目录中的所有文件(和目录)的列表?
当前回答
供参考添加扩展或ext文件的过滤器 进口操作系统
path = '.'
for dirname, dirnames, filenames in os.walk(path):
# print path to all filenames with extension py.
for filename in filenames:
fname_path = os.path.join(dirname, filename)
fext = os.path.splitext(fname_path)[1]
if fext == '.py':
print fname_path
else:
continue
其他回答
和我一起工作的是萨利赫在本页其他地方的回答的修改版本。
代码如下:
dir = 'given_directory_name'
filenames = [os.path.abspath(os.path.join(dir,i)) for i in os.listdir(dir)]
这是一种遍历目录树中每个文件和目录的方法:
import os
for dirname, dirnames, filenames in os.walk('.'):
# print path to all subdirectories first.
for subdirname in dirnames:
print(os.path.join(dirname, subdirname))
# print path to all filenames.
for filename in filenames:
print(os.path.join(dirname, filename))
# Advanced usage:
# editing the 'dirnames' list will stop os.walk() from recursing into there.
if '.git' in dirnames:
# don't go into any .git directories.
dirnames.remove('.git')
简单的方法:
list_output_files = [os.getcwd()+"\\"+f for f in os.listdir(os.getcwd())]
我写了一个很长的版本,包含了我可能需要的所有选项:http://sam.nipl.net/code/python/find.py
我想它也适合这里:
#!/usr/bin/env python
import os
import sys
def ls(dir, hidden=False, relative=True):
nodes = []
for nm in os.listdir(dir):
if not hidden and nm.startswith('.'):
continue
if not relative:
nm = os.path.join(dir, nm)
nodes.append(nm)
nodes.sort()
return nodes
def find(root, files=True, dirs=False, hidden=False, relative=True, topdown=True):
root = os.path.join(root, '') # add slash if not there
for parent, ldirs, lfiles in os.walk(root, topdown=topdown):
if relative:
parent = parent[len(root):]
if dirs and parent:
yield os.path.join(parent, '')
if not hidden:
lfiles = [nm for nm in lfiles if not nm.startswith('.')]
ldirs[:] = [nm for nm in ldirs if not nm.startswith('.')] # in place
if files:
lfiles.sort()
for nm in lfiles:
nm = os.path.join(parent, nm)
yield nm
def test(root):
print "* directory listing, with hidden files:"
print ls(root, hidden=True)
print
print "* recursive listing, with dirs, but no hidden files:"
for f in find(root, dirs=True):
print f
print
if __name__ == "__main__":
test(*sys.argv[1:])
试试这个:
import os
for top, dirs, files in os.walk('./'):
for nm in files:
print os.path.join(top, nm)
