So the REALLY cool thing about that module is the 44 line implementation of
it:

https://github.com/joshmaker/python-php/blob/master/php/__init__.py

It actually generates a php source file, passes in the arguments via a json
list, dynamically calls the referenced method within php, and returns the
output as json, and then calls the actual php interpreter on your system to
run it and return the result.

So it knows nothing about any PHP function, and does no mapping. The class
creates a "module-like object" (apparently all you need to do is implement
__getattr__) and then __getattr__ is called whenever you try to call a
method from the module.

Pretty cool!
Eric

Please add to the following:
Music to code by

    gentle distraction
        enough distraction to keep from getting stuck or bored
        not enough distraction to keep one from coding

    one person:
        person is to drown out noise coworkers and roommates
        instrumentals only, lyrics are distracting
        foreign language lyrics are not understood,
        so not distracting and thus OK

    another person does not care about lyrics,
    so is not distracted by them

    several folks need silence
    one folk needed silence for difficult coding,
    but music was helpful for most of other coding
    hard metal, no lyrics
        lame
        Animals as Leaders
    Brian Eno
    Siuguress(sp?????)
    Mike Oldfield (such as Tubular Bells)
    50's jazz
        Miles, Bird, Coltrane

    Rickie Lee Jones
        Pop Pop
        Ghostyhead
    Tom Waits

    Chet Baker
        Let's Get Lost

There was strong correlation between those who had read

and which side of the table they sit on.

There was also a strong correlation between those who needed silence
to code and those who music helped coding.

Subject: [CentralOH] Speakers needed for COhPy -- Please help
Message-ID: <CAJzarMOFz-LxSD9TEXaethNPeoh=KDnBEKrexVCpnvrVs=_Qtg@mail.gmail.com>

All,

We need speakers who would like to share with the group what they are doing
with Python, what interesting modules and libraries they have discovered,
or even just facilitate a discussion on a Python topic.

No topic is too small, no speaker too inexperienced. This is a friendly
group and Python family!

If you are planning a PyOhio talk, this would be a great place to practice
and get feedback (if you want feedback).

Please consider sharing your experience --- the group will benefit from it!

I'm looking for talks of any length, for any of the next few meetings.
Please contact me as soon as you can!

Thanks for your help!
Eric

I've missed a couple of the lunches because I'm unfamiliar with the area
and forget to hit google satellites early enough to find some parking
options.  May I suggest that future invites note a nearby location or
two, maybe the closest and the cheapest?

that neighborhood is far enough north that on street parking 
on a side street should be free (it is just south of North 
High School, at the southern boundry of Clintonville)

The weather was wonderful, which was good because of the very long line.
It paid to be early, which none of us were.
The line was long for good reason.
Four of us showed up at the same time, so we got to talk while waiting.

    Cleveland firm needs something done by hard deadline in mid-May,
    but keeps deferring hiring decision.

There were seven of us. One of us recognized someone else,
so there were another five Python folks there who had never heard of CohPy.
They thought we were joking about it being a Python lunch,
so we directed them to cohpy.org, and they confirmed that it was a real event.

Ray Ray's is in a parking lot and there was plenty of room to 
park one's carriage at Ray Ray's. 

I don't like to pay for parking.
That is reflected in the choice of locations.
I have avoided downtown lunches for fear of parking hassles or cost.
Although not a commitment for future lunches,
I think all of the lunches so far have had free parking available.

Many of the lunches are on Grandview Ave. 
There is free off-street parking available for all of those.
There is free parking beside Aladdin's and
hidden behind PhyPhomPho/Mazah/Halwani.
There is free on-street parking, one street to the west.

There are people looking for Raspberry Pi Zeros,
but they are hard to come by.
Demand has grossly outstripped supply.

I have a Raspberry Pi Zero, but am not using it,
so I will bring it to lunch to sell to someone else.

All,

Just a reminder that we have the April Python Challenge:

https://github.com/cohpy/challenge-201603-temps

So far there has been one entry and two others who have indicated to me
they will have an entry by Monday.

Anyone who submits an entry to the contest (even if it's just step 1) will
get a Python sticker of their choice.

And remember, whomever's program forecasts the closest high temperature for
the May COhPy meeting when I run the program next Monday will receive a
Python hat!

Looking forward to seeing everyone next Monday!

Cheers,
Eric

Need a good problem to solve with Python
for which regex is optimal[1] solution.
Then someone who eschews regexes
can show us an easier to read solution in Python (without regexes).

Eight folks showed up.

Python3 versus Python2

    not enough packages have been ported from 2 to 3,
    to do real projects

    However, in past year, enough packages _have_ been ported to Python3,
    that Python3 is feasible for most non-trivial projects.

Go To Statement Considered Harmful by Edsger W. Dijkstra
http://www.cs.utexas.edu/users/EWD/ewd13xx/EWD1308.PDF

Regexes considered harmful
    too hard to read

I often find problems for which regexes are the best solution,
in spite of them being hard to read.

Great teaching technique
a dad would bring something home and set it in front of kid.
When asked by kid about it, the dad would say that you'll figure it out.

Someone
stopped using regexes when started using Python instead of Perl.

    Regexes are OK on command line to search for something,
    but not if that regex is then handed to someone else.

Someone said:
"My goal is for the next person who reads my code to not hate me."

case statement considered harmful

    Case statement just not needed in Python.
    Use a dictionary of functions instead.

    Post a solution that uses case statement.
    Watch someone else rework that in Python.

As a bee-keeper for thirty years of so, I can assure the bees 
are not calm when they smell smoke, but rather appear 
agitated.  When smoke is present they quickly 'load up' with 
all the honey they can carry and exit a hive body, in what is 
no doubt an evolved [or intelligently designed] reaction to 
possible loss of hive contents to fire

> bees attack dark things
> beekeeping suits are white

I understand the assertion, but wonder at its implication of 
causation.  Perhaps rather as a hypothesis, bees attack things 
which look like common attackers: unwashed and furry forest 
creatures, and people in clothing other than [optically 
bright] and unusual white

Message-ID: <CAJzarMNAq6n29ONdRaPBexVSEO-+9U_CRrJGxOsmWABuS_G0Ag@mail.gmail.com>

In an effort to attract more technology companies and people to Columbus,
the Columbus Collaboratory is doing some research. Ben Blanquera asked me
to forward this survey, which should only take 5 minutes to complete, that
will help them understand why people relocate.

Thanks!


Original message:

*" Attracting talent to Columbus is high on the agenda for many in Columbus
and Ohio. " *

We at the Columbus Collaboratory <http://columbuscollaboratory.com/> are
conducting a study to understand the reasons why people relocate.

The purpose of this survey is to understand what factors are attractive and
unattractive when considering relocating for a job. We plan to use
responses to help us better attract people to the Columbus region. Data
will only be analyzed in aggregate and no individual data will be shared by
Columbus Collaboratory or Community Research Partners.

Please take 5 minutes to take the survey -

Have a great day!
Ben

https://github.com/cohpy/challenge-201603-temps/blob/master/README.md says in part:

    Given a month (say February), return a list of dates in that 
    month that the Central Ohio Python Users Group met 
    (in the case of February, it would return 2/22/2010, 
    2/28/2011, 2/27/2012, 2/25/2013, 2/24/2014, and 2/29/2015.

1. s%2/29/2015%2/23/2015%

2. Would it not return a date for this year?
   I.e., would it not return 2/29/2016?

Jim,

All correct, apparently I was still thinking it was 2015 :-). It should
return this year. I've corrected and pushed the fixes.

In the future, note that I accept pull requests!

Cheers,
Eric

Subject: [CentralOH] focus for numpy/scipy presentations
Message-ID: <20160430182741.2532ba807c2def625e3f9544@columbus.rr.com>

At the last cohpy meeting, several people wrote down numpy and/or scipy
as desired topics for future presentations.  These are very broad and
easily turn into boring overviews of python for matlab people.  Does
anyone have requests for a presentation on a specific scipy module,
digital signal processing topic, or even an idea for a project that you
heard numpy/scipy would be good for but not sure how to get started?

Played with refactoring a function from one of the previous challenges.
It was much fun.
