Python editor example with auto-complete?

[Robert Oschler]

Has anybody seen a python example that had auto-complete built in?  It seems
like it wouldn't be a horrendous job to provide at least current class level
only auto-complete for methods and attributes.  By auto-complete I mean,
you're in an edit window.  You type the name of a variable that is an
instance of some class, and as soon as you type a period ('.') a drop-down
list appears showing all the methods and properties for the class the
variable is an instance of. If you type characters after the period the list
auto-finds the closest match. Then you can select from the list and the
selection gets typed into the edit window after the period.

I figured if someone's done the work of the drop-down list and edit window
processing, might save some time, especially when it comes to the drop-down
list GUI handling.
