How to Remove Timestamp from Filenames in a Folder Using Python

If you're working with files on your computer, you might have encountered filenames that contain timestamps, making them cumbersome to manage. In this guide, we’ll provide you a straightforward way to remove these timestamps from filenames using Python. This process is particularly useful for beginners, so let’s take it step by step.

The Problem: Filenames with Timestamps

You may have a folder filled with files that look something like this:

[Dog]test 2021-04-01 22-12-01.txt

[Dog]test2 2021-02-01 22-22-01.txt

[Dog]test3 2020-05-01 22-23-21.txt

[Dog]test4 2020-02-07 22-22-31.txt

As you can see, the timestamps in these filenames make them less appealing and more challenging to work with. You might want to strip those timestamps down, ending up with cleaner filenames like:

test.txt

test2.txt

test3.txt

test4.txt

The Solution: Code Snippet to Remove Timestamps

Let’s break down the solution into easy-to-understand sections. Here’s what you need to do to remove those timestamps from the filenames in a folder.

Step 1: Basic Code for a Predefined List of Filenames

If you already have a predefined list of filenames as shown above, you can easily manipulate them. Here's a simple code snippet in Python that accomplishes this:

Explanation:

file[5:]: This part skips the first 5 characters of the filename, which includes the [Dog] prefix.

.split(' ')[0]: This splits the filename at spaces and takes the first part, effectively removing the timestamps.

'.txt': Finally, it appends the .txt extension back to the cleaned name.

Step 2: Handling Files from a Directory

If you want this code to apply to all the files in a directory without defining them manually, you can use the os library to list all files in a folder. Here’s how to do it:

Explanation:

os.listdir(path): This function retrieves a list of all items in the specified directory.

if file.endswith('.txt'): This ensures that we only process .txt files to avoid issues with other file types.

Conclusion

Now you have a clear understanding of how to remove timestamps from filenames in a folder using Python efficiently. With these simple code snippets, you can easily make your filenames cleaner and more manageable.

Feel free to adapt the code snippets to your specific needs, whether your files start with [Dog], [Cat], or any other prefix. With a little bit of practice, you’ll be able to control and customize your file management tasks effortlessly!
