How to Rename Files with Consecutive Dates Using Python

Managing files can sometimes be a challenging and tedious task, especially when it comes to ensuring that files are named in a clear and organized manner.

The Problem

Imagine that you have a series of image files named image0001.png through image000163.png. Each of these images corresponds to dates ranging from 01/01/2020 to 13/06/2020. However, all the files currently have the same date metadata, making it difficult to properly organize them based on their actual dates.

In this guide, we’ll explore a simple solution using Python that will allow you to rename these files sequentially, appending the corresponding date to each file name.

The Solution

To tackle this problem, we will utilize two primary Python modules:

os: This module provides a way to rename files.

datetime: This module will help us manage the date handling.

What You Need to Know

Script Location: Place the script in the same folder as your images. This will make it easier, as you won’t need to use absolute paths.

File Naming: You cannot use certain characters, like the trailing slash (/), in file names. We will use a dash (-) instead.

Step-by-Step Code

Let’s break down the code required to rename the files:

Explanation of the Code

Importing Modules: The first step is to import the necessary modules (datetime and os) to facilitate the renaming process.

Date Initialization: We initialize the date using datetime.datetime to start from 01/01/2020.

File Loop: Using a loop, we iterate through numbers 1 to 163.

File Naming: We construct the file name and format the date as dd-mm-yyyy.

Renaming the File: The os.rename function is used to rename the actual file on the system.

Update the Date: We increment the current date by one day in each iteration using datetime.timedelta.

Handling Different Number Formats

If the filenames do not follow a consistent pattern and could vary (e.g., 0001, 0002, up to 0100), we can use the rjust() method to ensure the filename remains properly formatted:

Alternatively, you can also utilize F-Strings with format specifications:

Conclusion

Using Python to rename files based on consecutive dates can save you a significant amount of time and help you organize your files more efficiently. This straightforward approach allows you to keep track of various files while ensuring they correspond accurately to the dates they represent.

With just a few lines of code, managing your file organization can become a task of the past!
