Here are a few. I'm sure people who know more about Python could
contribute more:
- Use keyword parameters with good default values when a method needs to
have an additional parameter. This allows old code to continue to work
while new code can pass in the extra information using the keyword.
- When an object is being passed into a method, and the method needs to
be changed to make use of some new characteristic of the object, use
reflection to determine whether the object has that characteristic. This
allows either old or new objects to be passed into the method.
- When a method needs to be renamed, keep around the old name by just
assigning it to the new method, i.e., oldfunc = newfunc.

Please elaborate, I'd certainly improve my own development.
