Uh. Try explaining this to newbies... ;)
On a second thought, the idea is quite usable considering some differences:
class Robot(object):
# as above
class Robots(dict):
def new(self, name):
new_robot = Robot(name)
self[name] = new_robot
return new_robot
def __getattr__(self, name):
if name in self:
return self[name]
raise AttributeError
robots = Robots()
robots.new('Bert')
robots.new('Ernie')
robots.Bert.sayhi()
robots["Bert"].sayhi()
for robot in robots:
robot.sayhi()
... etc ...
This doesn't include ugly globals() and exec "tricks".
