running multiple bash commands with subprocess

If I run echo a; echo b in bash the result will be that both commands are run. However if I use subprocess then the first command is run, printing out the whole of the rest of the line. The code below echos a; echo b instead of a b, how do I get it to run both commands? import subprocess, shlex def subprocess_cmd(command): process = subprocess.Popen(shlex.split(command), stdout=subprocess.PIPE) proc_stdout = process.communicate()[0].strip() print proc_stdout subprocess_cmd("echo a; echo b")
You have to use shell=True in subprocess and no shlex.split: import subprocess command = "echo a; echo b" ret = subprocess.run(command, capture_output=True, shell=True) # before Python 3.7: # ret = subprocess.run(command, stdout=subprocess.PIPE, shell=True) print(ret.stdout.decode()) returns: a b
