How do I list all files of a directory?

In Python, you can use the os module to list all files in a directory. The os.listdir() function returns a list of all files and directories in the specified directory.

Here's an example of how to use os.listdir() to list all files in the current directory:

List all files in the current directory using os.listdir() in Python

import os

files = os.listdir()
for file in files:
    print(file)

<div class="alert alert-info flex not-prose"> <span class="hidden md:block">Watch a video course </span> Python - The Practical Guide</div>

If you want to list the files in a specific directory, you can pass the directory path as an argument to the os.listdir() function:

List all files in a specific directory using os.listdir(path) in Python

import os

path = '/path/to/directory'
files = os.listdir(path)
for file in files:
    print(file)

You can also filter the files by their extension or other attributes using the python built-in functions such as filter, list comprehension and so on.

For example, you can use list comprehension to filter out only .txt files:

Filter files by extension using list comprehension in Python

import os

path = '/path/to/directory'
txt_files = [file for file in os.listdir(path) if file.endswith('.txt')]
for file in txt_files:
    print(file)

You could also use os.scandir() to get a iterator yielding os.DirEntry object that may have more information as well.

Get an iterator yielding os.DirEntry object in Python

import os
path = '/path/to/directory'
for file in os.scandir(path):
    if file.is_file():
        print(file.name)
