=>__name__ == 'const', so you´re actually doing
=>const = _const()

So how can I say this in const.py?

class _const:
    class ConstError(TypeError): pass
    def __setattr__(self,name,value):
        if self.__dict__.has_key(name):
            raise self.ConstError, "Can't rebind const(%s)"%name
        self.__dict__[name]=value

def __init__(self):
        sys.modules[self]=_const()

import sys

to cause a different instantiation a la

foo	= _const()

The goal would be to create different instances of consts.

I did try the previous suggestion

irrational_consts = _const()

but I got
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
NameError: name '_const' is not defined
*>>> iii=const()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: _const instance has no __call__ method

------------
For ref:

class _const:
    class ConstError(TypeError): pass
    def __setattr__(self,name,value):
        if self.__dict__.has_key(name):
            raise self.ConstError, "Can't rebind const(%s)"%name
        self.__dict__[name]=value

import sys
sys.modules[__name__]=_const()
