How to run bash script from python?

Question

Python

Hello.
Please tell me how to properly run the bash script that is on the computer through the telegram bot, which is written in python and get a response from it?
If you run the script itself through python, it works, but it crashes through the bot, I can’t figure out how to properly organize the output of the result.
In a normal python script, I did this:

import subprocess
subprocess.call("test.sh")

Answer 1

proc = subprocess.Popen('./test.sh', stdout=subprocess.PIPE)
output = proc.stdout.read()
print output

Answer 2

subprocess.call(['./test.sh'])
