Python – List Files in a Directory
ItsMyCode |
There are several modules available in Python to list files in a directory or folder. Some of the popular ones we can use are os, pathlib, glob, fnmatch , etc. This tutorial will look at the most popular way to list all the files in a directory.
We can use
os.listdir() to get all the files and directories in the specified path.Syntax – os.listdir(path)
It takes a path as a parameter and returns a list of all files and directories in a specified path.
# import OS module
import os
# List all the files and directories
path = "C:\Projects\Tryouts"
dir_list = os.listdir(path)
print("Files and directories in '", path, "' :")
# prints all files
print(dir_list)Output
Files and directories in ' C:\Projects\Tryouts ' :
['calc.py', 'etc', 'listindexerror.py', 'main.py', 'Python Tutorial.py', 'Python Tutorial.txt', 'test', 'test - Copy', ' __pycache__']The os module provides many functions to interact with operating system features, and one such method is
os.walk(), which generates the files and folders in a directory tree. It can traverse the tree either top-down or bottom-up search, and by default, it sets as top-down search.The
os.walk() also helps to retrieve the files and folder in the absolute path.# import OS module
import os
# List all the files and directories
path = "C:\Projects\Tryouts"
for (root, directories, files) in os.walk(path, topdown=False):
for name in files:
print(os.path.join(root, name))
for name in directories:
print(os.path.join(root, name))Output
C:\Projects\Tryouts\etc\password.txt
C:\Projects\Tryouts\test\python.txt
C:\Projects\Tryouts\test - Copy\python.txt
C:\Projects\Tryouts\ __pycache__ \calc.cpython-39.pyc
C:\Projects\Tryouts\calc.py
C:\Projects\Tryouts\listindexerror.py
C:\Projects\Tryouts\main.py
C:\Projects\Tryouts\Python Tutorial.py
C:\Projects\Tryouts\Python Tutorial.txt
C:\Projects\Tryouts\etc
C:\Projects\Tryouts\test
C:\Projects\Tryouts\test - Copy
C:\Projects\Tryouts\ __pycache__os.scan() method is available in Python 3.5 and above. scandir() accepts either a bytes or str object for the path parameter and returns the DirEntry.name and DirEntry.path attributes with the same type as the path.Syntax: os.scandir(path = ‘.’)
# import OS module
import os
# List all the files and directories
path = "C:\Projects\Tryouts"
data = os.scandir()
for item in data:
if item.is_dir() or item.is_file():
print(item.name)Output
calc.py
etc
listindexerror.py
main.py
Python Tutorial.py
Python Tutorial.txt
test
test - Copy
__pycache__The
glob module helps you retrieve the files/path matching a specified pattern as the glob supports the wildcard search. We can get both files and folders using the glob module.# import OS module
import glob
# List all the files and directories
path = "C:\Projects\Tryouts\*"
for file_name in glob.iglob(path, recursive=True):
print(file_name)
C:\Projects\Tryouts\calc.py
C:\Projects\Tryouts\etc
C:\Projects\Tryouts\listindexerror.py
C:\Projects\Tryouts\main.py
C:\Projects\Tryouts\Python Tutorial.py
C:\Projects\Tryouts\Python Tutorial.txt
C:\Projects\Tryouts\test
C:\Projects\Tryouts\test - Copy
C:\Projects\Tryouts\ __pycache__We can also print the filenames recursively using the
iglob()method. All you need to do is set the recursive parameter as true.Below the example, we use
iglob() method with recursive set to true and searching with a specific pattern to get all the .py files# import OS module
import glob
# List all the files and directories
path = "C:\Projects\Tryouts\*.py"
for file_name in glob.iglob(path, recursive=True):
print(file_name)Output
C:\Projects\Tryouts\calc.py
C:\Projects\Tryouts\listindexerror.py
C:\Projects\Tryouts\main.py
