Python App Detection

Lade detects your app as a Python app if an environment.yml, Pipfile, requirements.txt, or setup.py file is present in the root directory.

Specifying a Python Version

You can specify the Python version in your environment.yml file:

dependencies:
  - python=3.9

You can also specify the Python version in your Pipfile file:

[requires]
python_version = "3.9"

Alternatively, you can specify the Python version in your runtime.txt file:

python-3.9

Python Web Process

Lade will use the following priority order to determine the web process:

1. Procfile specifying the web process type
2. The Flask object specified in one of your Python files
3. The get_wsgi_application object specified in one of your Python files

For example, you can specify the get_wsgi_application object in your wsgi.py file:

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

Lade will automatically start your web application with the Gunicorn web server.
