I’m trying to create a container, it shows like it went good, but nothing shows, if i do a docker images there’s no image and either on the docker desktop app

the folder i want to make an image only contains this:

python.py
Dockerfile

and Dockerfile content is:
FROM python:3.9

WORKDIR /app

COPY python.py .

CMD [“python”, “python.py”]

the output if i do docker build -t prueabadocker . is:

sudo docker build -t pruebadocker .  1 ✘
