Python windows service pywin32

I recently set up a brand new Windows service implemented in Python, and although the experience was definitely easier than when I did it last ? First, most all? Secondly, the way to install self-contained Python programs on Windows has changed, and for the first time I used PyInstaller — which to be fair was a pretty smooth experience for the simple case, even though handling subprocesses and long-running processes took some effort.

There are two main parts to the service implementation — first there is the command-line helpers to allow you to install the service, and to allow Windows to manage it:. If there are any other arguments, assume that it is arguments to manager the service, e.

In both cases, we send our ServiceFramework subclass as a parameter. In this example MyService is just a class to handle the actual work sleeping… , in your own implementation it could be anything. I like keeping it entirely separate from the ServiceFramework implementation as it can quickly get complex. Creating a Windows executable using PyInstaller is reasonably straightforward:.

To fix this issue we can tell PyInstaller to include it:. Testing is important here — the build will succeed and then the program will fail in run time, so for complex application it becomes a case of trial and error — building, running to find any missing imports, then re-building after adding new --hidden-imports.
