Installation

Download Python

Open the official Python download page and choose the installer that matches your operating system.

Official Python downloads

If the page detects your system automatically, use that download button. Otherwise, choose the correct Windows, macOS, or Linux option from the download page.

Windows

You can check whether Python is installed and where it is installed from Windows PowerShell.

py -0p
py --version
py -c "import sys; print(sys.executable)"

py -0p lists the Python versions detected by the Windows Python Launcher and shows each executable path. The * mark shows the default Python selected by py. py --version checks the default Python version. The final command prints the exact Python executable used by py.

If several Python versions are installed and you need to target Python 3.14 explicitly, replace py with py -3.14.

macOS / Linux

Using Python 3.14 as the baseline, you can check whether Python is installed and where it is installed from the terminal.

python3 --version
which python3
python3 -c "import sys; print(sys.executable)"

python3 --version checks the installed Python version. which python3 shows the command path found by the shell. The final command prints the exact Python executable used by that python3 command.
