   I'd like to learn more about functional programming in Python than is
covered in Mark Lutz's "Learning Python." Please suggest web pages, pdf
docs, or books I should read.

This is all I could find of it, but I remember reading something similar to
this a while ago. It hours through how to construct church numerals in
python.

Search on itertools a lot for tutorials.  Anything lazy evaluation
tends to feel functional.

But then I always associate function with reading multi-dimensional
arrays as native primitives and pushing them through pipelines.  Is J
functional?  That's the one I'm most familiar with, inheriting from
APL.

The purists on math-thinking-l (a functionalist holdout) will likely
tell you to abandon ship before it's too late.

Python is their nemesis (sounds melodramatic), a an agile "imperative
language" and there's no salvaging it with "little lambda".

Basically, it's frustrating that code may get as difficult to untangle
as the ecosystems it models, whereas mathematically provably correct
code should be easier to maintain.

The functional purists find OO to "unprovable" so shy away.

But then I suppose all CS grads know this?  I'm tracking from a
philosophy angle (we like to watch the imperativists and
functionalists duke it out).

Hi Rich!

This may be slightly tangential to a functional Python overview, but I
just had to share this slide deck on generators. I've enjoyed using
the described "generators as pipeline" approach for my own log parsing
duties:

Love, love the practical (read: non-Fibonacci) examples.

Hey Pythoneers,

Tomorrow is the second Tuesday of the month, and we'll be gathering
for a social
meeting <http://www.meetup.com/pdxpython/events/23617051/> at Bailey's
Taproom <http://goo.gl/HL7Ok> at 6:30pm. Let's get together, enjoy the
beautiful weather, and share some beverages and Pythonic discussion.

Next month we'll be back on track with presentations, lightning talks and
Modules of the Month. If you have something you'd like to share, let me know
and I'll put you on the schedule for an upcoming meeting!

Bailey's Taproom is located at 213 Southwest Broadway. Here's a map:

Message-ID: <CAP7FcBwKhfbkV8RXwo4AS-FNJnNUcPs5sjKEhN_ww=GGyA341Q@mail.gmail.com>

Hey All!

Can you think of a COOLER job to tell friends and family about?  "I
work at Dark Horse, writing software for comics".  No more trying to
explain derivative calcs analysis or medical trend value reporting.
:)

We need flexible agile developers to join our team.  We're more
interested in fit and intelligence than your immediate skill laundry
list.  If that's enough to spark your interest, send your LinkedIn URL
to me (pcurtain at gmail.com and everywhere else).

What follows is the post I just added to Python Jobs.

Blessings!

Dark Horse Comics
http://www.darkhorse.com

**Job Description**:

Dark Horse Comics needs bright developers to join our in-house on-site
agile development team. Each of us codes freely among python and
django, objective-c, java, php and other tools.

**Requirements**

- Have a bright mind and a passion for software
- Have been coding in an OO language at least a year
- Know mobile (iOS and Android) or want to learn [2]

(second to those things)

- Python/Django for current web work, many frameworks and libs
- Javascript and HTML5/CSS (have you seen our Web Reader!?)
- Objective-C for our Dark Horse Comics reader app [2] and other iOS efforts
- Java for the Android version currently in development
- PHP for legacy apps waiting to be re-tooled [3]
- Linux/Xnix and AWS for servers, comfort with the shell is a must
- Various tools in our stuck including fabric, puppet, hudson,
mercurial, , raw SQL (still!) and more

**About the company**

We're doing *our* part to make the world safe for Digital Comics [1], [2]
and we need bright engineers to keep up the fight.

We offer
- An Agile/XP development environment
- Pairing and collaborative interaction
- Test-driven culture (still growing)
- FREE COMICS!
- Experience developing for Mobile and for Digital Media
- Low stress, sustainable pace
- We practice facilitated code reviews (using reviewboard currently).
- We use Pivotal Tracker for planning and during sprints.
- We provide Macs with second monitors decked out as each of us
prefer.  (Dark Horse is a top to bottom Mac shop)

Most of our development happens collaboratively, so being on-site in
our offices in Milwaukie is the norm, but hours and work styles are
flexible. Style is very casual, come as you are.
To apply, send an email with the URL to your LinkedIn profile.  If you have
links to Github/Bitbucket repos, portfolio sites and other examples of your
work, also good.  Tell us about your passion for software and one idea for how
to make the comics reading experience better.


**What Python is used for**: We **ARE** a Python shop. We use python for
all server work, site, services, automation and scripting.  Django is the
back end for our digital effort and the services behind the Dark Horse Comics
mobile reader application.
