Python Query 'module' object has no attribute 'test_func' -

I am trying to create a new module and method as part of the existing library.

The existing library is called Bly.Pht. I am creating a new * .i file in this directory which is named in Distance.py Distance.py I have:

  square distance: def __init __ (self, handle): self.handle = def def_func (t1, t2): print "executed correctly"   
 from the dragon shell, I do the following: Bly.Pht imports distance from  
  # This works fine dist = distance.test_func (input1, input2)   
 error me Makes  in the 'module' object, in particular Do not have 'test_func'   
 Is it possible to give any advice about this?  
 Many thanks.   
 
 
 You are not importing  distance  class, you are importing modules It consists of the  distance  class which can be fixed:  
  dist = distance.Distance.test_fund (input1, input2)   
 If you do not plan to include other functionality  Distance.py , the class definition may be  Bly / Pht / __ init __. There is a better idea to put in Py  or  Bly / Pht.py , in which case you could import it as you did it. (Unlike other languages, Python does not encourage each category of its own file).
