#) Don't write complicated classes that have similar APIs to dicts,
lists, etc. If it looks like a dict and smells like a dict, use a
dict. Don't write a bunch of boilerplate API. You can either
subclass a real dict, subclass UserDict (in rare situations), mixin
the UserDictMixin (spell? also in rare situations), etc., or just
provide access to the underlying dict.
#) Don't write getters and setters that don't actually do anything
except set a private instance member. If that's the case, just use a
public instance member. Later, you can switch to a real property
using the idiom in the Python cookbook
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/205183:
def foo():
doc = "property foo's doc string"
def fget(self):
return self._foo
def fset(self, value):
self._foo = value
def fdel(self):
del self._foo
return locals() # credit: David Niergarth
foo = property(**foo())
#) Need something? Use the online Python Cookbook ;) Got something
cool? Submit it to the cookbook. The code there isn't always
perfect, but it's usually a really good starting point!
Happy Hacking!
