Why does this AttributeError in python occur?

Question

There is one thing, that I do not understand.

Why does this

import scipy # happens with several other modules, too. I took scipy as an example now...         


        

Answer 1

The default namespace in Python is "__main__". When you use import scipy, Python creates a separate namespace as your module name. The rule in Pyhton is: when you want to call an attribute from another namespaces you have to use the fully qualified attribute name.
