How to Rename Folders Using Pandas and Python

Have you ever found yourself in a situation where your folder names aren't consistent, or maybe you'd just like to take a more uniform approach to naming? For example, if you have folders named Sub Folder A, Sub Folder B, and Sub Folder C, and you want to change them to lowercase names like sub folder a, sub folder b, and sub folder c.

This is not only a matter of aesthetics; consistent naming conventions can help keep your work organized and make it easier to navigate your directories. But how do you go about renaming folders in Python? Fortunately, there are several simple methods you can use, which we'll explore below.

Using shutil.move()

The shutil module in Python can help you move files or folders from one location to another and can also be used to rename them. Here's how you can use shutil.move() to rename a folder:

Step-by-Step Instructions

Import the module: First, you need to import the shutil module in your Python script.

Define old and new paths: You'll need to specify the current path of the folder you want to rename (old_path) and the new path with the new name (new_path).

Execute the move: Use the shutil.move() method to rename.

Here is a sample code snippet:

This will successfully rename Sub Folder A to sub folder a.

Using os.rename() with lower()

If your primary goal is to standardize the names of multiple folders to be all lower case, leveraging the os module could be the most efficient method. Here’s how you can do it:

Step-by-Step Instructions

Import the os module: Start by importing the os module.

Define the root folder: Specify the parent directory that contains the folders you want to rename.

Loop through the folder names: Use a loop to iterate through each folder in the parent directory.

Rename the folders: For each folder, its name can be converted to lowercase and renamed using os.rename().

Here’s a code example following these steps:

Key Points

The os.listdir() function fetches the list of all folders within a specified directory.

os.path.join() is used to combine directory names into a complete path.

The lower() method is called on the folder names to ensure they are converted to lower case.

Conclusion

Renaming folders can be a straightforward task when you're equipped with the right Python tools. Whether you opt for shutil.move() for direct renaming or os.rename() coupled with the lower() function for standardization, both methods allow you to easily maintain a clean and organized file structure.
