Calling an external command in Python

Question

Anonymous User · Answer

Look at the subprocess module in the stdlib:

from subprocess import call
call(["ls", "-l"])

The advantage of subprocess vs system is that it is more flexible (you can get the stdout, stderr, the "real" status code, better error handling, etc...). I think os.system is deprecated, too, or will be:

For quick/dirty/one time scripts, os.system is enough, though
