How do I list all files of a directory?

📝Tech Blog Post: The Ultimate Guide to Listing All Files in a Directory

📂Are you a Python enthusiast trying to navigate the world of directories and files? 🐍✨ Look no further! We have the solution to your problem. In this blog post, we will dive into the excellent way to list all files of a directory using Python and add them to a list. 📜🖥️

🤔 Why do you need to list all files in a directory? Listing all files in a directory is a common task in any programming project that deals with file manipulation. It allows you to gather information about the files in a given directory, iterate over them, analyze file names, or perform actions on specific file types.

💡Approach 1: Using the os module

The first approach we'll explore is using Python's built-in os module. This module provides a range of functions that allow us to interact with the underlying operating system. To list all files in a directory, we'll utilize the os.listdir() function.

Here's an example of how to use it:

import os

def list_files(directory):
    files = os.listdir(directory)
    return files

In the above example, we imported the os module and defined a function called list_files that takes a directory parameter. The os.listdir() function returns a list of all files and directories in the specified directory. We simply return this list, containing all the file names.

🌟Example

Let's say we have a directory called documents located at C:\Users\YourUsername\Documents. To list all files in this directory, we can use the following code:

files = list_files('C:\\Users\\YourUsername\\Documents')
print(files)

When you run the code, you will see a list of all the files in the documents directory printed in the console.

😎Easy, isn't it? You can now effortlessly list all the files in a directory using Python!

💡Approach 2: Using the glob module

Another approach is to use the glob module, which provides advanced pattern-matching functionality for file and directory searches. The glob.glob() function will allow us to filter files based on specific criteria, such as file extensions.

Consider the following example:

import glob

def list_files(directory):
    files = glob.glob(directory + '/*')
    return files

In the above code snippet, we imported the glob module and defined the list_files function. By using the glob.glob() function, we specify the directory path with "/*" to obtain all files within that directory. This approach provides more flexibility when dealing with specific file types.

🌟Example

Let's say you want to list all the .txt files in a directory called data. You can use the following code:

files = list_files('data/*.txt')
print(files)

When running the code, you will get a list of all the .txt files within the data directory.
