+Python Coding Standards
+=======================
+
+The Zen of Python
+-----------------
+
+Beautiful is better than ugly.
+Explicit is better than implicit.
+Simple is better than complex.
+Complex is better than complicated.
+Flat is better than nested.
+Sparse is better than dense.
+Readability counts.
+Special cases aren't special enough to break the rules.
+Although practicality beats purity.
+Errors should never pass silently.
+Unless explicitly silenced.
+
+In the face of ambiguity, refuse the temptation to guess.
+There should be one—and preferably only one—obvious way to do it.
+Although that way may not be obvious at first unless you're Dutch.
+Now is better than never.
+Although never is often better than right now.
+If the implementation is hard to explain, it's a bad idea.
+If the implementation is easy to explain, it may be a good idea.
+Namespaces are one honking great idea—let's do more of those!
+
+
+Use explicit imports
+--------------------
+
+Don't use:
+
+```
+from foo import *
+Bar()
+```
+
+Use:
+
+```
+from foo import Bar
+Bar()
+
+Or:
+
+```
+import foo
+foo.Bar()
