Python is an excellent open-source programming language widely used by programmers for developing versatile applications, including data visualization, web development, and machine learning. Despite Python’s exceptional performance, several errors arise when using the language, one of which is the ‘Ioerror: [Errno 28] No space left on device’ error.

This error is usually encountered when working with files in Python and indicates that there is no available storage space left on the device where the file is saved. It results from either insufficient physical storage or permission problems due to insufficient privileges. As a result, it is a common problem that programmers face and needs fixing to continue executing the program codes effectively.

If you have encountered this error while working in Python, worry less because this article presents some practical solutions to help you fix it. We will identify the reasons for the error and suggest different approaches on how to increase the storage capacity of your device or modify your Python code to overcome the problem. Trust me; you won’t want to miss it. Keep reading until the end!

When working with Python, you may encounter the error message IOError: [Errno 28] No space left on device. This error occurs when the disk partition where the program is trying to store data has run out of space. This error can be quite frustrating, especially if you have been working on a project for some time. In this article, we will explore different ways to solve this error.

Check Disk Space

Before attempting any other solution, it is important to check the disk space available. You can use the df -h command in the terminal to view the disk usage of your system. This command shows the disk space usage of each partition in human-readable format. If the partition where your Python program is running has low or no free space, then you need to free up some space. One way to free up space is to delete unnecessary files or move them to an external hard drive or cloud storage.

Use a Different Location

If you have access to another partition that has enough space, you can move your program to that location. If you are using Linux, you can mount an external hard drive or a network share to a directory in your file system. Once mounted, you can move your program’s files to that directory and run it from there. This solution is useful if you do not want to delete any files or if you need to keep the original location for some reason.

Reduce File Size

Another way to solve the IOError: [Errno 28] No space left on device error is to reduce the size of the files your program is working with. If your program is creating large files or reading large files into memory, it may be exhausting the available space in the partition. You can try to split large files into smaller chunks, use binary file formats, or compress your data using tools like gzip or zip. This solution may require you to modify your code, but it can significantly reduce the disk space requirements of your program.

Use Temporary Files

If your program is creating and deleting many small files during its execution, you may want to consider using temporary files. Temporary files are files that are created in a designated directory and deleted automatically when they are no longer needed. Python provides the tempfile module that allows you to create temporary files and directories. By using temporary files, you can reduce the number of files that your program creates and ensure that they are cleaned up properly, freeing up disk space.

Clear Cache

Some Python libraries and frameworks use cache files to speed up their operations. If your program is using a cache and the cache directory is located in the partition that has run out of space, you can clear the cache to free up some space. The exact method to clear the cache depends on the library or framework your program is using. For example, if you are using Django, you can use the python clearcache command to clear the cache.

Resize Partition

If you have exhausted all other options and still need more space, you can resize the partition where your program is located. This solution requires you to have administrative privileges and should be done with caution. You can use a partitioning tool like GParted to resize the partition. However, resizing a partition can cause data loss or corruption, so it is important to back up your data before attempting this solution.

Comparison Table

Solution Pros Cons
Check Disk Space Quick and easy May require deleting files
Use a Different Location Preserves existing files May require modifying code
Reduce File Size Reduces disk space requirements May require modifying code
Use Temporary Files Reduces number of files May require modifying code
Clear Cache Quick and easy May cause slower performance
Resize Partition Gains more disk space May cause data loss or corruption


The IOError: [Errno 28] No space left on device error can be frustrating, but there are several solutions that you can try. The best solution depends on the specific situation and requirements of your Python program. Checking disk space, using a different location, reducing file sizes, using temporary files, clearing cache, and resizing partitions are all viable solutions that you can use. By understanding the pros and cons of each solution, you can make an informed decision and solve the error with minimal disruption to your workflow.

Thank you for reading our article on how to solve Ioerror: [Errno 28] No Space Left On Device in Python. We hope that this guide has been helpful in resolving any issues you may have had with your Python program.

If you continue to experience the error, we recommend checking the disk space on your device and freeing up some memory. You can also try deleting unnecessary files or uninstalling unused programs to clear up additional space.

Remember that this error can occur for a variety of reasons, so it’s important to investigate the root cause of the issue. If you are still having trouble after following these steps, consider reaching out to the Python community for additional support and advice.

When encountering the error message Ioerror: [Errno 28] No Space Left On Device in Python, there are several questions that people may ask. Below are some of the common questions and their corresponding answers:

1. What does this error message mean?

  • This error message means that the program is unable to write to the disk because there is no more free space left on the device.
  • It can happen when trying to save a file or when working with large amounts of data that exceed the available storage capacity.

2. How can I fix this error?

  • The first step is to check the available disk space using the command df -h in the terminal.
  • If the disk is full, try deleting unnecessary files or moving them to an external device to free up space.
  • If the issue persists, consider increasing the storage capacity of the device or optimizing the code to use less memory.

3. Can this error be avoided?

  • Yes, this error can be avoided by regularly monitoring the available disk space and cleaning up unnecessary files.
  • It is also important to optimize the code to use less memory and handle large amounts of data efficiently.

By understanding the causes and solutions to the Ioerror: [Errno 28] No Space Left On Device error message, Python developers can effectively manage disk space and prevent program crashes.
