## Environment variables
### Environment variables

These environment variables become available after setup-python action execution:

| **Env.variable** | **Description** |
| ----------- | ----------- |
| pythonLocation |Contains the absolute path to the folder where the requested version of Python or PyPy is installed|
| Python_ROOT_DIR | https://cmake.org/cmake/help/latest/module/FindPython.html#module:FindPython |
| Python2_ROOT_DIR |https://cmake.org/cmake/help/latest/module/FindPython2.html#module:FindPython2|
| Python3_ROOT_DIR |https://cmake.org/cmake/help/latest/module/FindPython3.html#module:FindPython3|
| Env. variable | Description |
|----------------------|-------------|
| `pythonLocation` | Contains the absolute path to the folder where the requested version of Python is installed.<br><br>For **CPython**, the `python` executable is available at the root (e.g., `$pythonLocation/python` or `python.exe`).<br>For **PyPy** and **GraalPy**, the layout follows the upstream archive structure, so the executable may be found under `bin/` or `Scripts/`, depending on the platform. |
| `Python_ROOT_DIR` | https://cmake.org/cmake/help/latest/module/FindPython.html#module:FindPython |
| `Python2_ROOT_DIR` | https://cmake.org/cmake/help/latest/module/FindPython2.html#module:FindPython2 |
| `Python3_ROOT_DIR` | https://cmake.org/cmake/help/latest/module/FindPython3.html#module:FindPython3 |
