<div class="moz-text-html" lang="x-western"> Actually, the parethesis
mean "calling" the object.<br>
<br>
"Callable" objects can be of different types :<br>
-functions - in which case they get executed<br>
-classes (or metaclasses) - in which case they get "instantiated" (with
all the protocol : __new__(), __init__()...)<br>
-other objects - in which case they must contain a __call__ method with
will be executed when we use the parenthesis operator on the object.<br>
<br>
But a module is none of these : when you write "mymodule()", python
doesn't have a clue what he must execute/instantiate.<br>
<br>
Moduels aren't callable, but they can be "imported", simply by doing
"import mymodule", or "import mypackage.mymodule"<br>
Note that when you use packages, the modules that the package really
contains are searched with a protocol that can be rather elaborate, at
least (if I remember) the submodule name must be in the __all__
attribute of the package (i.e, the __all__ array defiend in the package
__init__.py file).<br>
<br>
I hope I haven't made you more confused with these quick explanations :p<br>

<pre wrap="">I am trying to get to the heart of what it is I am
missing. Is it the case that if you have a module C in a
package A:
A.C
that there is no way to load it such that you can use:
x = A.C()
in your code? This is just a simpler case of what I'm
trying to do now, which has a module C in a sub-package
to be imported:
A.B.C
ie with files:
mydir/A/B/C.py
mydir/mymain.py
and executed in mymain.py as:
x = A.B.C()
I may still chose to do it the way you suggested, but I
would still like to understand why this does not work.
