DESCRIPTION = (
    "A Dockerfile for a Python web application. It should use the python:3.9-slim "

    "expose port 8000, and run the application with uvicorn."
)

# Bug 1 (Syntax): Wrong escape character for multi-line RUN (using ^ instead of \)
# Bug 2 (Semantic): Wrong base image tag (python:3.9-slm instead of python:3.9-slim)
# Bug 3 (Runtime): Missing EXPOSE directive for the application port
