Not exactly. It's the * import mechanism her
Thanks to all

This way math doesn't get bound in the global namespace when doing
"from module import *"

Really, this questionable code is always mentioned as example in

It gives you an out in a case like

Another case:
try:
import json
except:
import simplejson as json
(same goes for several modules where the C implementation may or may not
be available)

import foo
f = foo
del foo
without the fiddling around. What the 'import... as' syntax gives is a

import foo as f
equivalent to
import foo
f = foo
Now, I was wondering about the usefulness in everyday programming of the
as syntax within an import statement. Here are some instances retrieved
from real code of such a syntax
