Specify shell=True as an argument and you can do anything you can do in a shell:
>>> commands = """echo hello ... echo hello | wc -l ... ps aux | grep python""" >>> b = subprocess.check_output(commands, shell=True) >>> print(b.decode('ascii')) hello 1 hugo 1255 1.0 0.6 777316 49924 ? Sl 09:14 0:08 /usr/bin/python2 /usr/bi hugo 6529 0.0 0.0 42408 7196 pts/0 S+ 09:23 0:00 python hugo 6559 0.0 0.0 10656 1128 pts/0 S+ 09:28 0:00 grep python >>> watch out though, accepting user input into the commands variable will lead to shell injection, which can be a dangerous security vulnerability.
