If you use \ and you don't add the r, you will get an error because the \ symbol will be treated as a special character.Īlternatively, you could replace the backslashes \ with forward slashes / in the path: > os.chdir("C:/Users/estef/Documents/FreeCodeCamp/freeCodeCamp News/9 - listdir vs system") Notice that I added an r before the absolute path to convert the string into a raw string. 'C:\\Users\\estef\\Documents\\FreeCodeCamp\\freeCodeCamp News\\9 - listdir vs system' > os.chdir(r"C:\Users\estef\Documents\FreeCodeCamp\freeCodeCamp News\9 - listdir vs system") This path starts from the root directory of your system. An absolute path specifies all the sequence of directories that you need to go through to reach your target directory.It can be either an absolute path or a relative path. You will need to specify the path to the new working directory, passing it as an argument, formatted as a string.

You can change your current working directory with this command from the os module: os.chdir()

The full path to the script (its location in the system, in the hierarchy of directories). I see: C:\Users\estef\Documents\freeCodeCamp\freeCodeCamp News\listdir vs system

If I run this command from a script, like this: import os This is the full path to my current working directory: 'C:\\Users\\estef\\AppData\\Local\\Programs\\Python\\Python38-32' From a Script If I run this command in the interactive shell (Windows), I see this: > os.getcwd() 💡 Tip: cwd means "current working directory." From the Interactive Shell This will show you the path to your current working directory. You can check your current working directory with this function from the os module: os.getcwd() Your current working directory, as the name implies, is the directory (folder) where you are currently working. Now let's see a very important concept that you need to know before you start working with listdir and system. prefix, like this: ()įor example: mkdir("New Folder") 🔹 Current Working Directory In this case, you can call the functions in your script as you normally would, without adding the os. įor example: from os import listdir, system If you are only going to work with one or two functions from the module, you can import them individually using this syntax: from import,. before the name of the function that you want to call, like this: os.()įor example: os.mkdir("New Folder") How to Import Individual Functions To be able to use the functions from the os module, you will need to add the prefix os. 💡 Tip: this module was already installed when you installed Python 3, so you will be able to use it immediately. This will give you access to all the functions defined in the os module. To import the os module, you simply need to include this line at the top of your Python script or run this line in the interactive shell: import os

#Python get files from directory code

We import a module when we want to use its code in our script. Importing a module means gaining access to all the functions and variables that are stored within the module. To use the os module in your script, you need to "import" it.

A module is a file that contains related Python code.

An example of a directory is your "Documents" folder.

A directory is what we commonly know as a "folder", where we usually store related files and/or other directories, creating a hierarchy of directories within directories that are called subdirectories.

Displaying the path to your current working directory.

This module includes functions that are used to interact with your operating system, performing actions like: The two functions that we will discuss: listdir() and system() belong to the os module.

Examples of both of them and how they work behind the scenes.

How to work with the system("ls") function and when to use it.

How to work with the listdir function and when to use it.

Then, we will dive into the functions themselves:

The difference between an absolute path and a relative path.

How to check and change your current working directory.

The concepts of "directory" and "current working directory".

The built-in Python os module and how to import it.

We will start by diving into concepts that are essential to work with listdir and system: If you want to learn how these functions work behind the scenes and how you can use their full power, then this article is for you.
