A dictionary with a fixed set of keys is better spelt as a class, e. g.
instead of the inner dictionary you can use something like
class Hooks(object):
def __init__(self, pre=None, post=None):
self.pre = pre
self.post = post
...
def before(): print "before"
def after(): print "after"
template["py"] = Hooks(before, after)
