Updating Python version from command prompt and Conversion from PyQt4 to PyQt5

[Vysero]

tried converting a simple Qt4 project into a Qt5 project

I didn't try converting a project. I am using 3.7.0. I you post code, I will try to convert. There's more to it than this package, is that correct? I also don't know anything about this package. It's not part of the PyPi repository, and hasn't been updated since May of last year.

Yeah the actual package seems to work just fine. I think the problem, in general, is that PyQt5 only works for 3.7 but I was hoping to figure out if that was for sure the reason before I updated python. I guess I am worried I might have to re-download all of my modules. I am new to python and therefore, I have never updated an existing version before.
