How can I find where Python is installed on Windows?

To find where Python is installed on Windows, you can use the where command in Command Prompt:

Find the default Python executable

C:\> where python
C:\Python38\python.exe

This prints the path to the Python executable.

If you have multiple versions of Python installed, the where command will show the location of all of them. You can specify a specific version of Python by including the version number in the command:

Find a specific Python version

C:\> where python3.8
C:\Python38\python.exe

This prints the path to the Python 3.8 executable.

Alternatively, you can use Python itself to print the executable path:

Check the active Python executable

C:\> python -c "import sys; print(sys.executable)"
C:\Python38\python.exe

This reliably returns the exact path of the Python interpreter being executed.
