Usage¶
os-traits is primarily composed of a set of constants that may be referenced
by simply importing the os_traits module and referencing one of the
module’s traits constants:
$ python
Python 2.7.11+ (default, Apr 17 2016, 14:00:29)
[GCC 5.3.1 20160413] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import os_traits as ot
>>> print ot.HW_CPU_X86_SSE42
HW_CPU_X86_SSE42
You can get a list of the os_traits symbols by simply doing a
dir(os_traits).
Want to see the trait strings for a subset of traits? There’s a method for that too:
>>> import pprint
>>> pprint.pprint(ot.get_traits(prefix='HW_CPU_X86_'))
