How to import X from Python library when X is defined in a package

[C. Barnes]

OK, here's the setup:

package/
__init__.py
X.py

python/lib/
X.py

Now inside package, we want to import the copy
of X.py defined in python/lib/.

In C one would do #include <X>

In Python, the easiest solution is:

Make a subpackage called pylibs

package/
__init__.py
X.py
pylibs/
__init__.py

In package/pylibs/__init__.py, do import X.

Then to get X from within package, just do

import package.pylibs.X

The more obvious solutions (such as doing
sys.path.reverse(); import X; sys.path.reverse()
inside the package) do not work, because Python
ignores sys.path
when inside a package (ie it always looks in the
package directory even when told explicitly not to).

Anyway, this is the workaround that I found, and it
works fine.
