This way math doesn't get bound in the global namespace when doing
"from module import *"
To contextualize more, I guess you are referring to the following
situation :
# a.py
import math as _math
# b.py
from a import *
print _math.sin(0) # raise a NameError
print math.sin(0) # raise a NameError
so the as syntax is also seful for hiding name, isn'it ?
