I hope to give a _little_ introduction to TDD at some Python meeting.

Please scrutinize https://github.com/james-prior/tdd-demo.git

That would be great. I talked to a few CentralOH members at pyOhio (or
maybe LinuxFest) about whether there was someone out there willing to teach
this. Any idea when as I am living in Findlay and have to plan ahead a bit.

So I'm learning Python and have become familiar with the basic syntax, but
I am struggling with how to write a try-except block for a project in an
online course that I'm taking.  Would anyone be able to help with this at
the lunch tomorrow?
Thanks,
Amy

Hi Travis, thank you so much for your offer to help with my code. I?ve had something come up and can?t make it to Smokehouse tonight, but I will plan to come to another Meetup in the near future. 
Happy (early) Thanksgiving,
Amy

I'll be there! Hope to see lots of Pythonistas there as well. It's free and
a great way to meet others in the local tech scene.

It's free, but  you do have to register at the link though.

Happy Thanksgiving!
Eric

tcl fibonacci code revisited:

    incr is faster than expr

For the most straightforward version, replacing the expr statement
with an incr statement reduced the execution time.

    jep at casual:~/20171123$ diff fib-with-braces.tcl fib-set-incr.tcl
    7c7,8
    <       set c [expr {$a + $b}]
    ---
    >       set c $a
    >       incr c $b
    jep at casual:~/20171123$ for program in fib-with-braces.tcl fib-with-braces-set-incr.tcl; do echo "$program ======================================================";echo 55555 | ./"$program";done
    fib-with-braces.tcl ======================================================
    Please enter seed value:
    Seed 55555; Result 90963...71278
    Duration 759501 microseconds
    fib-with-braces-set-incr.tcl ======================================================
    Please enter seed value:
    Seed 55555; Result 90963...71278
    Duration 594213 microseconds
    jep at casual:~/20171123$

For the version that used only two variables,
using incr instead of set...expr reduced the execution time,
but was still much slower than the straightforward versions.

    jep at casual:~/20171123$ diff fib-with-braces-without-c.tcl fib-with-braces-incr-without-c.tcl

Hi all,

It fills us with astronomical joy to announce the release of *poliastro
0.8.0*! ?

poliastro is a pure Python library that allows you to simulate and analyze
interplanetary orbits in a Jupyter notebook in an interactive and easy way,
used by people from all around the world.

This release brought a feature that has been in the making for several
years: an easy 3D plotting interface! Thanks to the new sampling methods
and the integration of Plotly and the Jupyter notebook, you can now plot
orbits in three dimensions and interactively rotate the view. Make sure to
check out the new notebook example here:

http://docs.poliastro.space/en/latest/examples/Plotting%20in%203D.html

On the other hand, we are proud to announce that we have been accepted as
an affiliated Astropy package, and that this work will be presented during
the first Open Source Cubesat Workshop at the European Space Operations
Centre in Darmstadt, Germany. As usual, you can read the full release notes
here:
