I downloaded a python script and a docker image containing commands to install all the dependencies. How can I run the python script using the docker image?

Copy python file in Docker image then execute -
docker run image-name PATH-OF-SCRIPT-IN-IMAGE/script.py
Or you can also build the DockerFile by using the RUN python PATH-OF-SCRIPT-IN-IMAGE/script.py inside DockerFile.

Can you explain how to copy the python file in the docker image?
Run in interactive mode:
docker run -it image_name python filename.py
or if you want host and port to be specified:
docker run -it -v filename.py:filename.py -p 8888:8888 image_name python filename.py

First, Copy your python script and other required files to your docker container.
docker cp /path_to_file <containerId>:/path_where_you_want_to_save
Second, open the container cli using docker desktop and run your python script.

The best way, I think, is to make your own image that contains the dependencies and the script.
When you say you've been given an image, I'm guessing that you've been given a Dockerfile, since you talk about it containing commands.
Place the Dockerfile and the script in the same directory. Add the following lines to the bottom of the Dockerfile.
# Existing part of Dockerfile goes here
COPY my-script.py .
CMD ["python", "my-script.py"]
Replace my-script.py with the name of the script.
Then build and run it with these commands
docker build -t my-image .
docker run my-image

@RishabGupta If it doesn't work, then please edit your post and add the Dockerfile you've got to it.
