This is my contribution here and I hope it will help someone. Most of us a totally newbie at least in "how to handle and manage" IDE and other stuff, so if you are like me, you hang on Dave's lips in his videos which is exactly their purpose. But unfortunately sometimes it can happen that for a triviality you stop, or worse still you go on without noticing a problem (certainly not Dave's fault, he can't predict every single case). I was proceeding with the CODEX course, when trying to recall the BLACK formatting from the terminal in VS CODE I get an error. Actually, I get the first error when starting the terminal itself, because it didn't load the CONDA environment correctly, even if the correct interpreter had been recognized and selected for the project.briefly, the environment variables were missing and thus the terminal couldn't execute the commands to start the correct environment. This happened because during the installation of Anaconda, not only was the creation of variables deselected by default, but it was also not recommended (even written in red). After a short and unsuccessful search for the correct variable, I settled on the good old reverse engineering approach: I made a user on test windows, installed anaconda with the addition of the environment variables and copied them (yes they were well more than one). I entered them in my main user, I restarted the pc and now it works correctly!Attached the list of variables. Now the call to BLACK works correctly, but the mystery remains because I can't find the first item to modify in the settings, to force the use of BLACK, it should be there by default with the installation of the Python extension I think (screenshot always attached)
