ImportError：没有名为b的模块-Python

Question

I was stuck with a code in python. But in simple form it looks like this

a.py looks like this

import b

def hello():
  print "hello"

print "a.py"
print hello()
print b.hi()

and b.py looks like this

def hi():
  print "hi"

a.py , i get an error. I know a couple of questions that address circular dependancies. But this is not that case correct? TIA - Edited

I've had a problem like this before and it was because I did not have an __init__.py in the same directory as the module/package I was trying to import. You need that file in order to import a package even if it's empty.
