Python

Detection

Python applications are detected when the application contains a requirements.txt or setup.py file in the root of your project directory.

Runtime

Currently, supported versions of Python are python-3.11.2, python-3.10.10, python-3.9.16, and python-3.8.16.

To specify the Python version to use, add a runtime.txt file in the root of your project directory with one of the versions mentioned above. For example, to use Python 3.8, your runtime.txt file must contain all three version number components (major, minor, and patch):

runtime.txt
python-3.11.2

If no version is specified, python-3.11.2 will be used.
