In your Python interpreter, type the following commands:
>>> import os, sys
>>> os.path.dirname(sys.executable)
'C:\\Python25'
Also, you can club all these and use a single line command. Open cmd and enter following command
python -c "import os, sys; print(os.path.dirname(sys.executable))"

If you have Python in your environment variable then you can use the following command in cmd or powershell:
where python
or for Unix enviroment
which python

Python Installation
The absolute maze that is installing python and path variables
Python and the PATH variable in Windows 10
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"
I've installed python on 1 computer successfully after hours of reading stackoverflow suggestions, youtube videos, documentation etc. And after getting it on there and working I was so frustrated and lost that I had no idea what actions from which source actually worked.
Can someone walk me through this from step 1 why python never works after running the installer and needs all sorts of pointer adjustments in the PATH variable or X other variable like PYTHON PATH to places I can't even manage to keep track of? More specifically, today with a fresh install, what needs to be done to get python to actually install and be detectable by commands.
I'm obviously new, and mostly illiterate to the command prompt so that's part of my difficulty with going through stack overflow where answers 1 through 5 all do something completely different all in command prompt with various opaque arguments, hidden references, implied actions, implied paths etc.
Do you remember checking the box in the image shown below to add your Python installation to PATH in Windows 10?
Adding Python to PATHWell, I was curious! What if someone accidentally forgot to check that little radio button? What would be the possible recovery steps?
So I spent my evening yesterday uninstalling Python and re-installing to figure out a way to add Python to the PATH post-installation.
If you forget to add Python to the PATH variable, you won't be able to run Python in your command line.
You will get a message saying,
‘python' is not recognized as an internal or external command.
Here are the steps I used to add Python to the PATH variable in Windows 10.
-
Copy the directory to which Python is being installed.
-
Search for System Properties in the Search Bar.
-
Click on the "Environment Variables" button in System Properties.
-
Click on the "Path" variable and then click on "Edit".
-
Now here's the deal. Paste the directory path from Step 1 at the top of the list. You can use the "Move up" button to get it to the top. Now click on "Ok".
I found out that if you paste the path at the end, it still doesn't work. Can someone tell me why?
Anyways, if the steps are not clear to anyone, here is a visual guide containing images of every step, on my blog for achieving the above objective. If you are interested, do take a look.
So I've been having trouble with Python and I want to know which installation I'm using (I have two user profiles on Windows, my old one and the one I made explicitly to code in, and they both have Python installed).
I tried looking it up, but it only led to this madness you see below:
