I am trying to create a utility module that only loads functions when
they are first called rather than loading everything.  I have a bunch
of files in my utility directory with individual methods and for each I
have lines like this in __init__.py:

def calc_tax(*arg, **name):
    from calc_tax import calc_tax as _func_
    calc_tax = _func_
    return _func_(*arg, **name)

This works the first time I call utility.calc_tax but if I call it
again I get a "TypeError: 'module' object is not callable" error.  Is
there any way to do what I want or do I have to put everything back
into a single file.  Of course, I can simply change all my calls to
utility.calc_tax.calc_tax(...) but I have a lot of code to change if I
do that.

Thanks.


You are stuck in a futile battle called "premature optimization". I would suggest that you stop worrying about any performance you would gain from doing something like this. Python has been "highly" optimized to handle imports in a very efficient way. Just put your functions in a file and import them.

from myfunctions import calc_tax, ...

Then you don't have to preface the function name with the module name.
