How to use `subprocess` command with pipes

Question

I want to use subprocess.check_output() with ps -A | grep \'process_name\'. I tried various solutions but so far nothing worked. Can someone guide

Answer 1

JKALAVIS solution is good, however I would add an improvement to use shlex instead of SHELL=TRUE. below im grepping out Query times

#!/bin/python
import subprocess
import shlex

cmd = "dig @8.8.4.4 +notcp www.google.com|grep 'Query'"
ps = subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE,stderr=subprocess.STDOUT)
output = ps.communicate()[0]
print(output)
