It’s called “Python’s Unlink Issue” and it’s not as scary as it sounds (or maybe it is).

So, what exactly is this unlink issue? Well, lets start with a little background. When you run Python scripts that generate .pyc files on Windows machines, those files are created in read-only mode by default. This can cause problems when trying to delete them using the `os.unlink()` function because it silently fails if the file is readonly.

Now, before we get into how this issue has been addressed (spoiler alert: there’s a fix!), lets take a moment to appreciate just how ridiculous this situation is. Imagine you’re working on a project that involves running Python scripts and generating .pyc files. You save your changes, run the script, and everything seems fine… until you try to delete those ***** .pyc files. Suddenly, you’re staring at your screen in frustration as Windows tells you it cant do what you want because those files are read-only.

But don’t be scared! The Python community has come to the rescue with a fix that will make your life easier (and less frustrating). In short, this fix involves adding a `chmod()` call before deleting the .pyc file using `os.unlink()`. This ensures that the file is writable and can be deleted without any issues.

Now, you might be wondering why this issue only affects Windows machines. Well, it turns out that on Unix-like systems (such as Linux or macOS), files are created with write permissions by default. So, there’s no need for a fix in those cases because the `os.unlink()` function works just fine.

But lets be real here: we all know that Windows is not Unix-like (sorry, Microsoft). And while this may seem like a minor issue to some of you, it can cause major headaches for developers who rely on Python for their work. That’s why the fix has been implemented in recent versions of Python and will hopefully be included in future releases as well.

The unlink issue is now officially resolved (at least for Windows users).
