Add a selected global python interpreter on to PATH

[ditordccaa]

Environment data

• VS Code version: 1.47.3
• Extension version (available under the Extensions sidebar): XXX
• OS and version: Windows Server 2019
• Python version (& distribution if applicable, e.g. Anaconda): Python 3.7.8 and Python 3.8.4 (downloaded from Python.org)
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): NA
• Relevant/affected Python packages and their versions:
• Relevant/affected Python-related VS Code extensions and their versions: Python 2020.7.96456 and Shell launcher 0.4.1
• Value of the python.languageServer setting: None

Expected behaviour

When I select the Python Interpreter version, I expect to get the selected version in the VSC integrated terminal.

Actual behaviour

When I type Python in the integrated terminal, the command is not recognized.
In my user settings, I'm setting the PATH environment variable (I removed the path for the python directory here). Also I'm excluding myself from the A/B pythonPath testing.

Steps to reproduce:

We do not participate in the terminal creation in terms of PATH. I also don't see any entry in your custom PATH setting that would place a python binary on your PATH. If you used the Python installer from python.org then you need to explicitly opt into putting Python on to the PATH to begin with.

What I will do, though, is turn this into a feature request to try to come up with a way to include a global Python interpreter into the terminal when one is manually specified.

Perfect. Makes sense. Thank you @brettcannon

[brettcannon]

@ditordccaa I'm reopening this to leave it as a feature request. If you aren't interested in it you can unsubscribe from the issue if you prefer.

We will want to address after #11039.

[karrtikr]

@luabud Should we close this as we're deciding to not do it right now?

We are afraid of breaking users if we were to implement this. Plus, we would rather encourage people to use environments which do have shell activation support.
