Python list directory tutorial shows how to list directory contents in Python. Multiple examples show how to list the directory contents and filter it.

Directory definition

Directory is an organizing unit in a computer’s file system for storing and locating files. Directories are hierarchically organized into a tree of directories. Directories have parent-child relationships. A directory is sometimes also called a folder.

Over the years, Python gained multiple APIs to list the directory contents. For instance, we can use the Path.iterdir, os.scandir, os.walk, Path.rglob, or os.listdir functions.

Python Path.iterdir

The Path.iterdir yields path objects of the directory contents. The children are yielded in arbitrary order, and the special entries ‘.’ and ‘..’ are not included.

listing.py

#!/usr/bin/python

from pathlib import Path

path = ‘.’

for path in Path(path).iterdir():

print(path)

The example lists the contents of the current directory. The listing is non-recursive and includes both files and directories.

$ ./listing.py recursive_glob.py list_dir_files2.py multiple_extensions.py walking3.py list_files.py temperatures.csv list_pandas.py src …

Python Path.iterdir list directories

The following example shows how to list only directories.

list_dirs.py

#!/usr/bin/python

from pathlib import Path

path = Path(’.’)

dirs = [e for e in path.iterdir() if e.is_dir()]

for dir in dirs: print(dir) #print(dir.parts[-1])

The example shows all immediate subdirectories of the current directory.

dirs = [e for e in path.iterdir() if e.is_dir()]

We build a list of directories using Python list comprehension. The is_dir returns True for a directory entry.

for dir in dirs: print(dir) #print(dir.parts[-1])

In a for loop, we print all the directories we have found. We can display the whole path or use the parts to display only a portion of the file.

Python Path.iterdir list files

The following example shows how to list only files.

list_files.py

#!/usr/bin/python

from pathlib import Path

path = Path(’/home/janbodnar/Documents/prog/python/')

files = [e for e in path.iterdir() if e.is_file()]

for file in files: print(file)

The example lists all files in the given directory. We use the is_file to check if an entry is a file.

Python Path.iterdir succint example

The following example shows a very succint code example.

list_files.py

#!/usr/bin/python

from pathlib import Path

home_path = Path.home()

print(*Path(home_path).iterdir(), sep="\n")

The iterdir returns a generator. With the * operator, we unpack it into arguments for the print function.

Python list directory with Path.glob

The Path.glob yields all the files that match the given simple pattern. The ** pattern means this directory and all subdirectories, recursively. For instance, the **/*.py finds all Python files in this directory and all its subdirectories.

globbing.py

#!/usr/bin/python

from pathlib import Path

path = Path(’.')

for e in path.glob(’*.py’): print(e)

The example prints all files which end in .py extension in the current directory.

$ ./globbing.py recursive_glob.py list_dir_files2.py multiple_extensions.py walking3.py list_files.py list_pandas.py list_files_modified.py recursive_scandir.py list_dir_files.py …

Python list directory recursively with Path.rglob

The Path.rglob is a convenience call for Path.glob with **/ added in front of the given relative pattern.

rglobbing.py

#!/usr/bin/python

from pathlib import Path

path = Path(’/home/janbodnar/Documents/prog/python/')

for e in path.rglob(’*.py’): print(e)

for e in path.glob(’**/*.py’):

print(e)

The example finds all Python files in the given directory and all its subdirectories. The commented code does the same job.

Python list directory with multiple extensions

The following example lists all files with three possible extensions.

multiple_extensions.py

#!/usr/bin/python

from pathlib import Path

path = Path.cwd()

files = { p.resolve() for p in Path(path).glob("**/*") if p.suffix in [’.py’, ‘.csv’, ‘.txt’] }

for file in files: print(file.parts[-1])

The example lists all .py, .csv, and .txt files.

files = { p.resolve() for p in Path(path).glob("**/*") if p.suffix in [’.py’, ‘.csv’, ‘.txt’] }

We use a set comprehension to build a set of files with the provided extensions.

$ ./multiple_extensions.py data_2019.csv walking.py list_files.py data.txt multiple_extensions.py scan_dir.py list_files_size.py list_pandas.py temperatures.csv recursive_glob.py list_dir_files2.py data.csv …

Python list directory with os.scandir

The os.scandir was introduced in Python 3.5 with the aim of improving performance and to mitigate some limitations of the older os.listdir.

The scandir function returns directory entries along with file attribute information, giving better performance for many common use cases.

scan_dir.py

#!/usr/bin/python

import os

path = ‘.’

with os.scandir(path) as it:

for entry in it:

    if entry.is_file():
        print(entry.name)

The example list all files in the current working directory.

Python list directory recursively with os.walk

The os.walk walks the given directory recursively; it yields a 3-tuple (dirpath, dirnames, filenames).

walking.py

#!/usr/bin/python

import os

path = ‘/home/janbodnar/Documents/prog/python/’

for dirpath, dirs, files in os.walk(path):

for file in files:

file_name = os.path.join(dirpath, file)

if file_name.endswith('.py'):
    print(file_name)

The example lists all Python files. To check if a file is a Python file, we use the endswith function.

Python list directory recursively with os.scandir

The os.walk returns an iterator of os.DirEntry objects corresponding to the entries in the directory given by path.

recursive_scandir.py

#!/usr/bin/python

import os

def scan_recursive(path):

with os.scandir(path) as it:
    
    for entry in it:
        if entry.is_file():
            yield entry.name
        else:
            yield from scan_recursive(entry.path)

for e in scan_recursive(’/root/Documents/prog/python/’): print(e)

The example uses the scandir function alongside the generator and recursion patterns to recursively find all files in the given directory.

Python Path tree

The following practical program outputs the contents of the specified directory in a hierarchical tree structure.

path_tree.py

#!/usr/bin/python

from pathlib import Path

def generate_tree(directory):

print(f'+ {directory}')

for path in sorted(directory.rglob('*')):

    depth = len(path.relative_to(directory).parts)
    spacer = '    ' * depth

    # print(f'{spacer}+ {path.name}')

    if path.is_file():
        print(f'{spacer}f {path.name}')
    else:
        print(f'{spacer}d {path.name}')

path = Path.home() / ‘Downloads’

generate_tree(path)

The example generates a directory tree from the Downloads directory.

Python list directory files by size

The following example lists files filtered by size.

list_files_size.py

#!/usr/bin/python

import os from pathlib import Path

path = Path.home() / ‘Downloads’

size = 102410241024

large_files = [e for e in path.rglob(’.’) if e.is_file() and os.path.getsize(e) >= size]

for file in large_files: print(f’{file} {os.path.getsize(file)}’)

The example prints all files that are greater than 1GB in the Downloads directory. We use the path.rglob to walk recursively and the os.path.getsize to determine the file size.

Python list diretory by modification date

The following example lists all files by modification date.

list_files_modified.py

#!/usr/bin/python

import os import datetime

now = datetime.datetime.now() ago = now - datetime.timedelta(minutes=30)

path = ‘/home/janbodnar/Documents/prog/python/’

for root, dirs, files in os.walk(path):

for fname in files:

    path = os.path.join(root, fname)
    st = os.stat(path)
    mtime = datetime.datetime.fromtimestamp(st.st_mtime)

    if mtime &gt; ago:
        print(f'{path} modified {mtime}')

In the example, we list all files that have been modified in the last 30 minutes. We use the os.stat function to get the modification date of a file and the os.walk to list the contents.

Python list directory with os.listdir

The os.listdir returns a list containing the names of the entries in the directory given by path. The list is in arbitrary order, and does not include the special entries ‘.’ and ‘..’.

This is older API and it is generally recommended to use more recent APIs for directory listings.

list_dir.py

#!/usr/bin/python

import os

path = ‘.’

files = os.listdir(path)

for file in files: print(file)

The example lists all files and directories in the current directory.

list_files2.py

#!/usr/bin/python

import os

dirs = filter(os.path.isfile, os.listdir())

print(tuple(dirs))

In this example, we list all files in the current working directory. We use the built-in filter and the os.path.isfile functions.

Python fnmatch with os.listdir

The fnmatch module provides support for Unix shell-style wildcards. They are not the same as regular expressions.. The special characters used in shell-style wildcards are:

    Pattern
    Meaning



    *
    matches everything


    ?
    matches any single character


    [seq]
    matches characters in seq


    [!seq]
    matches characters not in seq

Table: The fnmatch special characters

The fnmatch function takes the filename and the pattern as parameters.

list_csv.py

#!/usr/bin/python

import fnmatch import os

path = ‘.’

for file in os.listdir(path):

if fnmatch.fnmatch(file, '*.csv'):
    print(file)

In the example, we list all CSV files.

$ ./list_csv.py temperatures.csv data_2019.csv data.csv

We have three CSV files in the directory.

Python directory contents in table with Pandas

Pandas is a Python data analysis and manipulation tool. The following example shows the directory listings in a Pandas DataFrame.

list_pandas.py

#!/usr/bin/python

import pandas as pd from pathlib import Path import time

path = Path.cwd() all_files = []

for e in path.rglob(’.’): all_files.append((e.name, e.parent, time.ctime(e.stat().st_ctime)))

columns = [‘File_Name’, ‘Parent’, ‘Created’] df = pd.DataFrame.from_records(all_files, columns=columns)

print(df.head(5))

In the example, we show file names, their suffix and creation date for the first file entries in a Pandas DataFrame.

$./list_pandas.py File name Suffix Created 0 recursive_glob.py .py Fri Sep 11 13:04:54 2020 1 list_dir_files2.py .py Fri Sep 11 12:50:22 2020 2 multiple_extensions.py .py Fri Sep 11 16:09:30 2020 3 walking3.py .py Fri Sep 11 13:06:31 2020 4 list_files.py .py Fri Sep 11 14:23:47 2020

Python directory contents in table with PrettyTable

PrettyTable is a Python library for generating simple ASCII tables.

list_pretty_table.py

#!/usr/bin/python

from prettytable import PrettyTable from pathlib import Path import time

pt = PrettyTable()

path = Path.cwd() all_files = []

pt.field_names = [‘File name’, ‘Suffix’, ‘Created’]

for e in path.rglob(’.’):

pt.add_row((e.name, e.suffix, time.ctime(e.stat().st_ctime)))

print(pt)

We show the file names of the current directory, their suffix and creation date in a table generated by PrettyTable.
