POPython strange import behavior: import x.y works, from x import y doesn't
text
Body
copied!<p>I am having a simple directory structure, like that:</p> <pre><code>MyProject --main.py --lib #that's a directory/package ----__init__.py ----view.py ----common_lib.py ----other irrelevant modules... </code></pre> <p>In main.py:</p> <pre><code>from lib import view </code></pre> <p>causes the following error:</p> <pre><code>ImportError: cannot import name view </code></pre> <p>If instead, I write it like:</p> <pre><code>from lib.view import * </code></pre> <p>This import passes successfully, but next failure happens in view.py, in that:</p> <pre><code>from common_lib import Comments, Locations, ScreenData, ProgressSignal </code></pre> <p>causes:</p> <pre><code>ImportError: No module named 'common_lib' </code></pre> <p>And as it appears from the directory structure, common_lib.py resides in the same directory as view.py, how can it happen that it cannot be found? How does it come that 'from x import y' doesn't work, and 'from x.y import *' works? '<code>__init__.py</code>' is completely empty BTW. And I am using Python 3.3 32-bit.</p> <p>What is more annoying, this same program worked 2 days ago.I was testing some code in IDLE and when I thought the code was ready to include in the project, pasted it into PyDev, I was shocked by this error. I changed nothing about my directories or modules.</p> <p>Also, still more strangeness, running view.py and common_lib.py as standalone (without being imported) runs just fine. It should produce the error if any issues really existed.</p> <p>Thanks. Any advice is highly appreciated.</p>
