cross platform – How can I find the current OS in Python?

If you want user readable data but still detailed, you can use platform.platform()

>>> import platform
>>> platform.platform()
Linux-3.3.0-8.fc16.x86_64-x86_64-with-fedora-16-Verne

platform also has some other useful methods:

>>> platform.system()
Windows
>>> platform.release()
XP
>>> platform.version()
5.1.2600

Heres a few different possible calls you can make to identify where you are

import platform
import sys

def linux_distribution():
  try:
    return platform.linux_distribution()
  except:
    return N/A

print(Python version: %s
dist: %s
linux_distribution: %s
system: %s
machine: %s
platform: %s
uname: %s
version: %s
mac_ver: %s
 % (
sys.version.split(n),
str(platform.dist()),
linux_distribution(),
platform.system(),
platform.machine(),
platform.platform(),
platform.uname(),
platform.version(),
platform.mac_ver(),
))

The outputs of this script ran on a few different systems (Linux, Windows, Solaris, MacOS) and architectures (x86, x64, Itanium, power pc, sparc) is available here: https://github.com/hpcugent/easybuild/wiki/OS_flavor_name_version

e.g. Solaris on sparc gave:

Python version: [2.6.4 (r264:75706, Aug  4 2010, 16:53:32) [C]]
dist: (, , )
linux_distribution: (, , )

machine: sun4u
platform: SunOS-5.9-sun4u-sparc-32bit-ELF
uname: (SunOS, xxx, 5.9, Generic_122300-60, sun4u, sparc)
version: Generic_122300-60
mac_ver: (, (, , ), )

or MacOS on M1

Python version: [2.7.16 (default, Dec 21 2020, 23:00:36) , [GCC Apple LLVM 12.0.0 (clang-1200.0.30.4) [+internal-os, ptrauth-isa=sign+stri]

I usually use sys.platform to get the platform. sys.platform will distinguish between linux, other unixes, and OS X, while os.name is posix for all of them.

For much more detailed information, use the platform module. This has cross-platform functions that will give you information on the machine architecture, OS and OS version, version of Python, etc. Also it has os-specific functions to get things like the particular linux distribution.

import os
print os.name

This gives you the essential information you will usually need. To distinguish between, say, different editions of Windows, you will have to use a platform-specific method.
