Thanks for all the great suggestion.
First of all, Carl is right that it does not take much to impress a
java programmer about the expressiveness of functional programming.
Covered map, reduce and filter as Rainer suggested.
Emphasized the advantages of functional style as summarised by Steve
D'Aprano.
I showcased the use of groupby() in itertools. Think about what it
takes to implement similar logic in Java. Also introduced the gotcha
of using groupby(): you must first sort the list in the same way you
want to group them by.
Then I got ambitious and tried to introduce partial(). I basically
lost everyone right there. They can understand what partial does but
do not know why it can be useful. My example was too trivial and it
did not help. What is the best way to introduce partial/currying?
See my response to Kurian -- Partial Function Application -- just a few
minutes ago.
