To check if Python is installed on Windows, open Command Prompt or Windows PowerShell and run the command python --version (or python -V). If Python is installed, the system will display the version number (e.g., Python 3.14.x); if not, you will receive an error message or be redirected to the Microsoft Store.
Alternatively, you can search for "Python" in the Windows Start Menu. If installed, the app will appear as a top result; pressing Enter will launch the Python prompt (>>>), confirming the installation. For systems with multiple versions, the py --version command or py --list can identify all installed Python interpreters.
Open Command Prompt > Type Python Or py > Hit Enter If Python Is Installed it will show the version Details Otherwise It will Open Microsoft Store To Download From Microsoft Store
Just go in cmd and type where python if it installed it will open a prompt .
Sometimes it may not work if environment variable is not set up, so you can also check by where python in cmd. If where python returns something hot to that path and see for python.exe

All of the comments guided me to the right way to do it.
I used this great working code:
:: Check for Python Installation
python --version 3>NUL
if errorlevel 1 goto errorNoPython
:: Reaching here means Python is installed.
:: Execute stuff...
:: Once done, exit the batch file -- skips executing the errorNoPython section
goto:eof
:errorNoPython
echo.
echo Error^: Python not installed
"C:\Program Files\used\systems\innoventiq\accumanager\required\excutables\python-3.7.3-amd64.exe"

Python noob here, my particular use case requires a 32 bit python. I've installed it (I think it is) but would like to double check. There is no information in the install file properties about this - is there a way to find out?
Your computer has python3.8 installed. To quickly check whether python2 is installed, run the command python2 --version, and your computer will most likely show command not found, because it is most likely not installed in your system.
Use the command sudo apt install python2 to install python2.
Also, in the recent versions of Ubuntu, python2 has to be called with the command python2, not just python.
Warning: Do not try to remove python3, or change the default Python version to 2. python3.8 is preinstalled in your version of Ubuntu, and major components of Ubuntu depend on it. You can safely have both python2 and python3 installed.
You can check using python2 --version for python2 and python3 --version for python3. You can also use which python to verify which python will be used when called. Apparently it is installed in your machine, but yarn could not find it.
