If you come from a Java background, you should read these two articles:

http://dirtsimple.org/2004/12/python-is-not-java.html
http://dirtsimple.org/2004/12/java-is-not-python-either.html

Everybody should read this:

https://realpython.com/blog/python/the-most-diabolical-python-antipattern/

Stop writing classes:

Start writing classes:

http://lucumr.pocoo.org/2013/2/13/moar-classes/

Contradiction? No, not really. You should understand when to write a class
when not to write a class. If you force everything to be in a class, you're
living in the Kingdom of Nouns:

(discusses the Java model of "everything must be in a class")


Nearly everything by Raymond Hettinger, starting with these:

Read the Python source code:

https://rhettinger.wordpress.com/2011/01/28/open-your-source-more/

(Older modules might not show "best practice" any more, but you can still
learn something from them.)

At the interactive interpreter, read the Zen of Python:

import this

What programming experience do you have? I'm thinking of languages.

Here are a few of my guidelines - most not Python specific:

Keep logic and data separate.

Comment early and often - but don't comment the obvious.

Use meaningful names.

Read the manuals.

Get familiar with modules. Someone has likely already solved the problem.

Do not override built-in names.

Follow these email lists.

Avoid things like "if valid == True:".
"if valid:" is sufficient.

Read the manuals.

When asking for help:
  Use a problem-specific subject.
  Use plain text so code keeps indentation
  Mention your Python version and OS.
  Include any traceback.

If something is not clear try it in the interactive window.

Dictionaries are very useful. Get familiar with them.

HTH.

Pylint is your friend: http://www.pylint.org/

If you already know a bit about the language then a good place to start 
is the Google Python Style Guide:
