`write /dev/stdout: broken pipe` when calling docker run from python

I have given python script :

import os

os.popen(f'docker run --rm -t --link mosquitto-server ruimarinho/mosquitto mosquitto_pub -h mosquitto-server -t "test_topic" -m "{message}"')

Now, this script works as expected, docker command is executed, but every time i run this line given error appears in terminal:

write /dev/stdout: broken pipe

Can someone please help me get rid of it? I did search for solution but every post is about docker only and no already posted solution works for me.

Use os.system() if you're not going to read the pipes opened by os.popen(). Using os.system() will not redirect output, though. If you need that, you could try e.g. subprocess.check_output() (which reads them for you).
