Redirect subprocess to a variable as a string

If you're using 2.7, you can use subprocess.check_output():

>>> import subprocess
>>> output = subprocess.check_output(['echo', '640x360'])
>>> print output
640x360

If not:

>>> p = subprocess.Popen(['echo', '640x360'], stdout=subprocess.PIPE)
>>> p.communicate()
('640x360\n', None)

import subprocess
p = subprocess.Popen(["ls", "-al"], stdout=subprocess.PIPE)
out, err = p.communicate()
print out
