POHow do I make these relative imports work in Python 3?
text
Body
copied!<p>I have a directory structure that looks like this:</p> <pre><code>project/ __init__.py foo/ __init.py__ first.py second.py third.py plum.py </code></pre> <p>In <code>project/foo/__init__.py</code> I import classes from <code>first.py</code>, <code>second.py</code> and <code>third.py</code> and put them in <code>__all__</code>.</p> <p>There's a class in <code>first.py</code> named <code>WonderfulThing</code> which I'd like to use in <code>second.py</code>, and want to import by importing <code>*</code> from <code>foo</code>. (It's outside of the scope of this question why I'd like to do so, assume I have a good reason.)</p> <p>In <code>second.py</code> I've tried <code>from .foo import *</code>, <code>from foo import *</code> and <code>from . import *</code> and in none of these cases is <code>WonderfulThing</code> imported. I also tried <code>from ..foo import *</code>, which raises an error "Attempted relative import beyond toplevel package".</p> <p>I've read the docs and the PEP, and I can't work out how to make this work. Any assistance would be appreciated.</p> <p><strong>Clarification/Edit:</strong> It seems like I may have been misunderstanding the way <code>__all__</code> works in packages. I was using it the same as in modules,</p> <pre><code>from .first import WonderfulThing __all__ = [ "WonderfulThing" ] </code></pre> <p>but looking at the docs again it seems to suggest that <code>__all__</code> may only be used in packages to specify the names of modules to be imported by default; there doesn't seem to be any way to include anything that's not a module.</p> <p>Is this correct?</p> <p><strong>Edit:</strong> A non-wildcard import failed (<code>cannot import name WonderfulThing</code>). Trying <code>from . import foo</code> failed, but <code>import foo</code> works. Unfortunately, <code>dir(foo)</code> shows nothing.</p>
