How to get container stats details using python docker

Question

I am trying to get the docker container stats inside my python code after running the container as shown below. I am referring to python docker SDk https://docker-py.readthedocs.io/en/stable/index.html to run and get the details of container.

container = docker_client.containers.run(image = image,entrypoint = entrypoint,detach=True,tty=False,volumes = {FILE_PATH+input_file:{'bind': '/src/input.txt', 'mode': 'rw'}})
container.wait()
data = container.stats(stream=False)

The stats which are getting doesn't have memory and few other details properly. Below are the stats details

import os
os.system("docker stats $(docker ps -q) --no-stream")

if you want to get the stats of all the running container then the following command will help you. Otherwise you need to calculate the stats yourself from total used so can be tricky .
