(1) Newlines are allowed inside an open (, [, or {. So:

p = subprocess.Popen(
    shlex.split(cmd),
    stdout=subprocess.PIPE,
    stderr=subprocess.PIPE)

Other techniques:

(2) Introduce helper variables:

cmd = shlex.split(cmd)
p = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

(3) Import names:

from subprocess import PIPE
p = subprocess.Popen(shlex.split(cmd), stdout=PIPE, stderr=PIPE)

(4) Use aliases:

import subprocess as sp
p = sp.Popen(shlex.split(cmd), stdout=sp.PIPE, stderr=sp.PIPE)
