What is the difference between os.system and subprocess module in Python?

Question

Both are used to call system commands inside Python ..but what are the notable differences and how to pipe commands in both of them.

Answer 1

<< You should use subprocess. Not that it makes any difference, it's just newer module intended to replace os.system (have a look at this section [ http://docs.python.org/2/library/subprocess.html#replacing-os-system ] for a drop-in replacement). It also has more features in case you need them one day.

In short: there is no reason to use os.system (except for compatibility with older versions of Python). >>
