How to organize a program update?

Question

PyQt

Hello. Wrote a small program with a graphical interface. In the future I want to release several updates to this program. Hence the question, how can the process of updating the program be organized so that the user does not have to constantly re-download the .exe file? For example, at startup, the program checks if there are updates, if so, it downloads this update.

This is done through simple parsers. Which send requests to hosting with a file. For example, you can do it so that version data is stored in some file on the hosting, so that before downloading, first compare versions from a text file. And if they differ, then simply download the desired file, and overwrite it instead of the existing one.

On the same forum, a couple of topics ago, they advised this library:

In the future, I advise you to start all the same with trying to find the answer yourself, at least within the same forum, not to mention independent use of google
