x is now bound to the module x, not the class within the module. The 
class is an attribute of the module: x.X
>  x = X()
Should be
   anX = x.X()

Don't reuse the name x, you lose the binding to the module and you won't 
be able to create any more x.X.

This is basic Python stuff, you might want to look at a tutorial such as
http://docs.python.org/tut/node8.html

or one of the beginner tutorials here:

If you want use the class X write this:
  
  from x import *  (x if yor archive is x.py and X if your archive is X.py)
  
  
  now the program y.py look's somting like this:
  
  from x import *
  a = X()
   a.hello()
  
  another form to use your library:
  
  import x (x if yor archive is x.py and X if your archive is X.py)
  a=x.X()
   a.hello()

 Example:
 ---------------------- X.py----------------------
 class X:
  def hello():
   print "Hello"


 ---------------------- Y.py----------------------
 import X
 x = X()
 x.hello()


 I get TypeError: call of non function (module 'X')
 Both files are in the same directory.

 Tanks!

This is generally considered bad style. It makes it hard to figure out 
where definitions come from in the importing program, and can lead to 
surprises where you import more than you intend.

This is much better. You can also use
   from x import X

if you don't want to have to type the module name everywhere you use X.
