How to Change Working Directory in Python | phoenixNAP KB (2024)

Introduction

A working directory is where a Python script looks for and saves files during execution. Changing the working directory in Python is essential for efficient Python file handling and management.

The process simplifies code and improves productivity when going through the file system.

This guide shows how to change the working directory in Python.

Prerequisites

• Python 3 installed and configured.
• A Python IDE or text editor to write code.
• The os module for communicating with the operating system.

Get Current Working Directory in Python

The getcwd() function from the os module fetches the current working directory location. The function returns the full path starting from the root directory to the current working directory. The working directory is where a Python script executes all the commands.

The syntax is:

os.getcwd()

To check the current working directory, import the os module and print the getcwd() function's results. For example:

import osprint(os.getcwd())

If using a text editor, save the code and run the script with the following command:

python3 [filename].py

The code prints the current working directory of the script.

Change Current Working Directory in Python

To switch the current working directory in Python to a different location, use the chdir() function from the os module and provide the absolute path as a string. The syntax is:

os.chdir('[path]')

To test how the function works, import the os module and print the current working directory. Change the location using the chdir() function and print the working directory again.

The example below demonstrates how to change the working directory:

import osprint(os.getcwd())os.chdir('[path]')print(os.getcwd())

The code prints the working directory before and after the change. The current working directory changes to the location provided in the chdir() function.

Alternatively, save the path as a string and provide the variable to the function. For example:

import ospath = '[path]'print(os.getcwd())os.chdir(path)print(os.getcwd())

Storing the path string in a variable allows storing multiple locations in different variables at the beginning of the code. Multiple variables can reside in a list, which enables looping through the list and changing directories with ease.

Conclusion

After reading this guide, you know how to check the current working directory and change it to a different location. Python uses the os module to communicate with the underlying operating system to commit the changes.
