python finding mac os build number

Question

How can I find my Mac OS X build number? And if possible, is there a way to find it using Python? I would like to use Python so that I can automatically make OS X .app files in an automated fashion.

EDIT: I see the 'Marked as duplicate' messages, and realize that people think that I mean the Mac OS X VERSION number. I'm talking about the BUILD number.

Answer 1

Oddly enough, the OS X build number does not seem to be available through the platform module. OS X does provide a sw_vers command which can be used to retrieve the build number through os.popen.

Example:

import os
print(os.popen("sw_vers -buildVersion").read().strip())

Output on OS X 10.9.4 Mavericks:

13E28

Not ideal, but it works!

Answer 2

Try the platform module? It will get you just about everything Python knows about the version of the OS, as well as info about the Python interpreter itself.
