learning python idioms

[conkerll at gmail.com]

After several years developing in Java, I've begun to switch to Python
for several of my new projects as I have found the language quite
interesting.  I've read several tutorials and implemented a few sample
programs and I've found that Python enables one to program in a variety
of different styles (I'm not sure if this was the original intention or
not).  Thus, I find myself occaisionally slipping into the "Java"
mindset when writing Python code and I wonder if this is not optimal.
Python is not Java and there must be more "correct" ways of doing this
in Python that simply writing Java code with different syntax.  Is
there a good reference on the internet about Python-specific idioms and
just good Python style in general.  Which language constructs are
efficient and which aren't?

Thanks in advance,
Ben
