That would be Fred, right? HE could show us... (*)
If I were him I'd be afraid to show off my coding skills

really cared for roasted lambda chops. ;->
ROFL!
Actually, I am not afraid to show my programming skills, as I have done
so in various programming courses I've taught in the past.
Alas, my Python prowess is *not* current, as I have not written much
Python since the time series pattern "sniffers" I wrote during my
day-trading days that would scour trading data for statistically
significant recurring patterns. These Python scrips would run all night
long looking for exploitable trading patterns in all the major
securities and give me a report in the morning a few hours before the
market opened.
It was truly a wonderful system, integrated with MySQL, Java, and C++
running on a cluster of 5 computers, and would -- on my custom-written
real-time charts -- alert me when that pattern re-emerged and show it to
me graphically *on the chart itself*.
Having the patterns that were, say, successful 70% of the time was one
thing. Being able to execute the trades based on those patterns was
quite something else. 70% success rate also meant a 30% failure rate,
and knowing when a trade was failing or succeeding was pretty tough,
especially when you have 10s of thousands of dollars on the line.
Anyway, enough of my rambling and reveling in "the good old days." If I
get back into Python anytime soon, I'll be more than happy to give a
talk on it.
Actually I have a new language in mind I'd like to write, something
highly experimental, that would basically put OOP on steroids. I hope to
be able to do that soon. Functional Programming would definitely play a
role, but that role would be minor in lieu of what I hope to accomplish.
Giving away my secrets; gotta stop doing that! :-)
