I've aways been under the impression that direct use of __dict__ was
discouraged. Something along the lines of __dict__ being an
implementation detail while getattr and hasattr are the proper
interfaces. But I might be wrong.

Hello everyone,
I have a quick python question. Is they a better way of calling a
method dynamically then what I have below? Is there a more elegant
approach? Thanks in advance.
try:
push = getattr(self, 'get_%s_content' % self.name)
except AttributeError:
raise "Method does not exist"
