Reference current module?

[Tobiah]

Can I do:

getattr(current_module, 'foo')

where 'current_module' is a handle the the one
that the code is in? Just like

getattr(self, 'foo')

in a class, but for the current module instead?

Thanks,

Toby

You can try __import__() with __name__::

>>foo = 42
mod = __import__(__name__)
getattr(mod, 'foo')

42

The python-list archives
<URL:http://mail.python.org/pipermail/python-list/are your friend.

Google is able to search within a site hierarchy by using search terms
like the following:

site:mail.python.org/pipermail/python-list/ current module reference

Searching there, I immediately find this brief thread:

A simple way would be using sys.modules[__name__].
But I prefer using globals()['foo'] as it is simpler and does not assume
additional requirements (like __name__ still being the same, or the module
still available for importing).

In this case I really wanted a reference to
the actual module, so that I could walk down
from there in a sort of object mapping:

def remote_call(call = 'foo.bar.other.thing'):
destination_object = sys.modules[__name__]
for part in call.split('.'):
destination_object = getattr(destination_object, part)
