Since you are working with windows, you can specify python version with python absolute path as mentioned previously or with python launcher (which is installed with python) with py
command.
you can list installed python versions with py -0
then you can get output similar to this:
Installed Pythons found by py Launcher for Windows
-3.9-64 *
-3.8-32
-3.7-64
-3.6-64
-2.7-64
Then you can specify python version you want by typing it as listed.
python3
command is almost used in linux os which have installed python 2.x so python
refer to python 2.x and python3
refers to python 3.x.
