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
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')
其他回答
这是另一种选择。
os.scandir(path='.')
它返回os的迭代器。对应于path指定目录中的条目(以及文件属性信息)的DirEntry对象。
例子:
with os.scandir(path) as it:
for entry in it:
if not entry.name.startswith('.'):
print(entry.name)
Using scandir() instead of listdir() can significantly increase the performance of code that also needs file type or file attribute information, because os.DirEntry objects expose this information if the operating system provides it when scanning a directory. All os.DirEntry methods may perform a system call, but is_dir() and is_file() usually only require a system call for symbolic links; os.DirEntry.stat() always requires a system call on Unix but only requires one for symbolic links on Windows.
Python文档
下面是一行python版本:
import os
dir = 'given_directory_name'
filenames = [os.path.join(os.path.dirname(os.path.abspath(__file__)),dir,i) for i in os.listdir(dir)]
这段代码列出给定目录名中所有文件和目录的完整路径。
试试这个:
import os
for top, dirs, files in os.walk('./'):
for nm in files:
print os.path.join(top, nm)
你可以使用
os.listdir(path)
参考和更多的操作系统函数看这里:
Python 2文档:https://docs.python.org/2/library/os.html#os.listdir Python 3文档:https://docs.python.org/3/library/os.html#os.listdir
import os
for filename in os.listdir("C:\\temp"):
print filename
