Ooops. Just did a quick test, and you need to double up the
backslashes one more time when using os.system(). I think
there might also be a way to supress the chatter coming out of
TeX, but if you're using subprocess, you can just attach stdout
and stderr to a bitbucket. Here's a demo where label1.tex has
no errors and label2.tex has an error:
________________________testit.py____________________________________
import os
ret1 = os.system('latex \\\\batchmode\\\\input %s' % 'label1.tex')
print ret1
ret2 = os.system('latex \\\\batchmode\\\\input %s' % 'label2.tex')
print ret2
