A trouble with VS Code

[adt]

It should only be "python": "$pythonPath $fullFileName", no {}.

The outcome of trials with json file at my end has been as follows:

TEST-01:

"python": "$pythonPath $fullFileName"

Mouse hover over above entry in json file elicits the following message:

Unknown Configuration Setting

Closing the json file & loading a python file, attracts two messages as follows:

Sorry something went wrong. Activating Intellicode supprt for python

And

Extension activation failed. Run the 'Developer:oggle Developer Tools'

Simultaneously, at bottom left corner of task bar, there is indefinite turning of circular arrow saying "Python extension loading - -"

However, code execute successfully on pressing Ctrl+Alt+N

TEST-02:

"code-runner.executorMap": "python": "$pythonPath $fullFileName"

OR

"code-runner.executorMap": "python: '$pythonPath $fullFileName'"

OR

"code-runner.executorMap": "python: $pythonPath $fullFileName"

In json file, mouse hover tip:

Incorrect type. Expected "object"

Code does not execute. Message on trying to Run python file:

Code language not supported or defined

TEST-03:

"python.pythonPath": "$pythonPath $fullFileName"

With the above entry in json file, the code executes without any problem.

At present, there is only one version of python on my Windows-10 desktop. As suggested by you, following code was run:

import sys  
print(sys.executable)

The output is as follows:

Output:
[Running] python -u "j:\AdtPython-Practice\00-RoughTesting.py"
C:\Program Files\Python37\python.exe

[Done] exited with code=0 in 0.124 seconds
