获取目录中所有文件的绝对路径

If the argument given to os.walk is absolute, then the root dir names yielded during iteration will also be absolute. So, you only need to join them with the filenames:

import os


for root, dirs, files in os.walk(os.path.abspath("../path/to/dir/")):
for file in files:
print(os.path.join(root, file))

You can use os.path.abspath() to turn relative paths into absolute paths:

file_paths = []


for folder, subs, files in os.walk(rootdir):
for filename in files:
file_paths.append(os.path.abspath(os.path.join(folder, filename)))

os.path.abspath makes sure a path is absolute. Use the following helper function:

import os


def absoluteFilePaths(directory):
for dirpath,_,filenames in os.walk(directory):
for f in filenames:
yield os.path.abspath(os.path.join(dirpath, f))

Try:

import os


for root, dirs, files in os.walk('.'):
for file in files:
p=os.path.join(root,file)
print p
print os.path.abspath(p)
print

I wanted to keep the subdirectory details and not the files and wanted only subdirs with one xml file in them. I can do it this way:

for rootDirectory, subDirectories, files in os.walk(eventDirectory):
for subDirectory in subDirectories:
absSubDir = os.path.join(rootDirectory, subDirectory)
if len(glob.glob(os.path.join(absSubDir, "*.xml"))) == 1:
print "Parsing information in " + absSubDir

If you have Python 3.4 or newer you can use pathlib (or a third-party backport if you have an older Python version):

import pathlib
for filepath in pathlib.Path(directory).glob('**/*'):
print(filepath.absolute())

from glob import glob




def absolute_file_paths(directory):
return glob(join(directory, "**"))

for root, directories, filenames in os.walk(directory):
for directory in directories:
print os.path.join(root, directory)
for filename in filenames:
if filename.endswith(".JPG"):
print filename
print os.path.join(root,filename)

All files and folders:

x = [os.path.abspath(os.path.join(directory, p)) for p in os.listdir(directory)]

Images (.jpg | .png):

x = [os.path.abspath(os.path.join(directory, p)) for p in os.listdir(directory) if p.endswith(('jpg', 'png'))]

Try:

from pathlib import Path
path = 'Desktop'
files = filter(lambda filepath: filepath.is_file(), Path(path).glob('*'))
for file in files:
print(file.absolute())

Starting with python 3.5 the idiomatic solution would be:

import os


def absolute_file_paths(directory):
path = os.path.abspath(directory)
return [entry.path for entry in os.scandir(path) if entry.is_file()]

This not just reads nicer but also is faster in many cases. For more details (like ignoring symlinks) see original python docs: https://docs.python.org/3/library/os.html#os.scandir

Try This

pth=''
types=os.listdir(pth)
for type_ in types:
file_names=os.listdir(f'{pth}/{type_}')
file_names=list(map(lambda x:f'{pth}/{type_}/{x}',file_names))
train_folder+=file_names
