VSCode: The term 'python' is not recognized...but py works

Question

I just installed python on VS Code and I can't run any python code using python command.

python command:

Running the code seems to run python command by default and it does not recognize it.

When I right click and choose Run Code it complains:

'python' is not recognized as an internal or external command, operable program or batch file

Same goes for manually running python main.py.

When I open an elevated PowerShell and run python, it complains:

python : The term 'python' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ python
+ ~~~~~~
    + CategoryInfo          : ObjectNotFound: (python:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

py command:

It doesn't try to use py command but it recognizes it. And when I manually call py main.py, it works.

When I manually do >py main.py it writes my Goodbye, World!

Question:

How can I make it compile/run in VS Code simply by using the CodeRunner's right-click feature (Run Code)?

---

I already have both Python folder and its Scripts folder in PATH.

I'm using VS Code 1.27.2 and I have installed python 3.7.0 on my machine and have checked its installer checkbox for adding the environment variables automatically. (PATH is ok)

I also installed : ms-python.python and tht13.python and formulahendry.code-runner extensions on the VS Code.

This is my main.py code:

print("Goodbye, World!")

Answer 1

It turned out that I just had to restart my computer after I installed ms-python.python and tht13.python and formulahendry.code-runner extensions on the VS Code and added python's Scripts folder in PATH.

Now both py and python commands work from anywhere like cmd or Run Code in the right click menu.
