Python import error "module 'factory' has no attribute 'fuzzy'"

I'm a fresher in factory_boy. In my code, I import factory and then used this import to access the fuzzy like factory.fuzzy then it shows error as module 'factory' has no attribute 'fuzzy'.

I solved this problem by again importing like this
import factory from factory import fuzzy

by doing so there were no errors.

What is the reason for this!
