oh!, the one i own has C++ examples.
The other day i was just wondering, java has a
java.lang.Runnable interface just to wrap a run() method bcos functions/
methods are not
first class citizens.

Does command pattern make sense to Python?
wIn java, we normally have classes implementing a Command Interface and we
normally store
all those instances in a hashtable/equivalent and invoke the Command method.

I guess Python w'd just store the method objects or function objects in a
dict and
achieve the same effect.

Can someone discuss other patterns which do not make sense / can be easily
done using Python?
