__all__.extend(['subpackage1','subpackage2'])<br><br>My question is the following: I need to import an external package, say numpy, for use in various submodules. So far, I simply do an import numpy as _numpy where needed, say sub1module1 and sub2module2. This means that I import this package a number of times which doesn't seem to be a logical thing to do (?). In the end, I would like to make this module a "global" module for my library.<br><br>I would find it more practical to simply do this import in the __init__ of rootlib and then use it directly in the submodules as rootlib._numpy calls, but I'm not sure exactly how to do this because it would mean that I would have to do an import rootlib in my subpackages which doesn't sound so good...<br><br>Can anyone give me a hint ?<br><br>Cheers,<br><br>Auré<br><br></div>
