Python

Detection

Python applications are detected when the application contains a requirements.txt, poetry.lock, or Pipfile.lock file in the root of your project directory.

Runtime

Currently, supported versions of Python are 3.13, 3.12, 3.11, 3.10, and 3.9.

To specify the Python version to use, add a .python-version file in the root of your project directory with one of the versions mentioned above. For example, to use Python 3.13, your .python-version file must contain all three version number components (major, minor, and patch):

3.13.0

If no version is specified, Python 3.13 will be used.
