The Python Developers Guide specifically states to get VS2017 for developing or enhancing python on a Windows system.

Is it still correct to specifically use VS2017 , or is VS2019 also acceptable?

We have to update the devguide. VS 2019 is supported, probably even recommended, as long as the C++ tools are v14.x.

Thank you Łukasz, I was hoping that would be the answer. How does one verify whether the C++ tools are 14.x, or is that just the usual for recent versions of VS2019? Peter

When you're installing Visual Studio the C++ tools version is listed under the selected components as "v14x". However, at this stage, the *only* version in circulation is 14.x - mine shows v142. Until the 14 changes to a "15", it will be binary compatible and so you can use any version at all to build CPython and/or extension modules. Our official releases are always using relatively up-to-date compilers, but provided the compatibility is maintained on Microsoft's side, there's no need to worry about the specific versions.
