There are more UNICES than Linux.
As I wrote in an earlier post IMHO os.name is the
better choice, because it just spits out 'posix'
for all the different UNICES out there.

Same principle applies.

sys.platform
'osf1V4'

So your code would fail on my machine, while
it understands "clear" perfectly well.

IMHO clearing the screen at the beginning of a console program
is a bad habit. You loose information and gain nothing.
