Re: [portland] looking back on recent Python haps and recent Luciano's visit
Thanks for the kind words Kirby and Stephen! Looking up the PDX PUG was the best thing I did in this trip. I had I great time presenting to you and drinking beer afterwards. I am specially grateful to Paul M who kindly hosted me at his place with his wonderful family. Also thanks to everyone else who offered me places to stay when I asked. You rock! And if you ever come to São Paulo, let me know. I hope to see you all next year at PyCon!

I really enjoyed Luciano's talk at the PDX Python event night and immediately got Fluent Python afterwards. I haven't gotten all the way through it but so far I think it's a great book for taking people from good Python programmers to excellent Python programmers. As an aside, I'd also like to remind people that the Portland Python Users Group works with O'Reilly and that you can get a 50% discount off of eBooks and 40% off of print books (including Fluent Python) by using the discount code PCBW on their site. -Bracket On Sat, Aug 22, 2015 at 9:41 AM, kirby urner kirby.ur...@gmail.com wrote: Followup: I really enjoyed both talks Luciano gave at OSCON. My college-age daughter is deeply into using Arduinos and such for serious science [1] and is studying Python both in her college and through O'Reilly where I work. I wrote to her about Pin.go right away. As a perk of my job I also get Safari Books On-Line where Luciano's new O'Reilly book, Fluent Python, has recently appeared. I'm finding it really useful and apropos given my day job as a Python mentor. Lots of details I've wanted to study up on but as too lazy to do so, are now succinctly summarized for me, such as how hashing works and the relationship of __hash__ and id etc. I've always been impressed by the emerging Pythonista subculture in Brazil and Luciano reinforces my admiration. Two OSCONs ago I hung out with Tatia from Brazil, who's dad is a professor of literature. She was really excited by my i18n focus and hopes of getting more of our own curriculum in Portuguese in a way customized for Brazilian mentors.

Re: [portland] PEP 8 Line Length Compliance
Of course in the first syntax rule I mention I should have said:
Whenever you open a parenthesis, brace or bracket, every newline is
considered as plain space by the parser UNTIL YOU CLOSE THE
PARENTHESIS, BRACE OR BRACKET.
Which is rather obvious...

There are two syntax rules of Python that are not so well-known that
help avoiding the \:
- Whenever you open a parenthesis, brace or bracket, every newline is
considered as plain space by the parser. Very often, adding
parenthesis around an expression does not change it's meaning, so
that's one way to make one logical line span multiple physical lines
without resorting to \.
- Two or more string literals with no intervening tokens except
whitespace are parsed as a single string literal.
Putting those two rules together, the result is that this snippet:
text = ('a bb ccc e '
'ff ggg ')
Is exactly the same as this one, as far as the Python interpreter is
concerned:
text = 'a bb ccc e ff ggg hh'
But note that I appended a trailing space to the first string literal,
otherwise the parser would see this:
text = 'a bb ccc eff ggg hh'
HTH.

Should I just ignore that PEP 8 suggestion or is there a line continuation
character (such as \) that can be applied?

Unless the string is delineated with single quotes (as in a content list for a drop-down picklist control). :-) The syntax I described works for any of the valid string delimiters in Python: single quotes, double quotes, triple single quotes and triple double quotes, and the adjacent string literals do not need to use the same delimiter, you can mix and match and they'll still be parsed as one big string literal. I'm used to seeing (and writing) newlines in bash scripts and other text so now I know python recognizes it I can use this solution. The problem with the trailing \ is if someone accidentally types a space after it, the newline is no longer escaped, and most editors don't highlight this error, so you get a confusing message from the interpreter.

[portland] Python author wants to speak to Portland-PUG and needs sofa for 2 nights
Dear Portland Pythonistas, I am the author of Fluent Python [1] and I'm going to present two exciting talks at OSCON 2015 (exciting for me, at least...). [1] http://shop.oreilly.com/product/0636920032519.do The talks are: - Plate spinning: Modern concurrency in Python - Pingo means pin, go!: Universal IoT programming in Python You can read more about me and the talks at my OSCON speaker page: http://www.oscon.com/open-source-2015/public/schedule/speaker/150170 I've previously presented at PyCon US, OSCON and many Python community events. I'd live to present one or both of these talks to your group when I am in Portland for OSCON 2015 from July 22-24. I'd also like to extend my stay at Portland until Sunday, July 26th, so I am looking for a place to stay Friday and Saturday night (July 24, 25). This is not a trade: the offer to speak at a Portland Meetup while I am in Portland stands, even if I can't find a place to crash Friday and Saturday. Our dates would just be a bit more limited.

Re: [portland] Python author wants to speak to Portland-PUG and needs sofa for 2 nights
Thank you very much, Kirby! Paul M offered to host me about 11 minutes before your kind message. I'd love to exchange ideas about Python fluency with you and everyone else! Even if there is no timely Portland PUG meetup, we could just go out for a beer and celebrate the international Python community!

Cheers, Luciano Greetings Luciano -- I will give you first dibs if I can confirm quarters. I have a spare room that would work well, but then its former occupant, now in Nepal may need it for a few days this summer and has yet to say exactly when (no round trip booked yet). I have a comfortable wood frame house and plan to be attending OSCON myself so will be transportation-aware (car or public are the two options). My by-then 21 year-old daughter and 86-year-old mom also expect quarters during OSCON but their space is assured already. It all depends on Lindsey, an avid student of Newar / Devanagari language Buddhism who really wants to stay there for some years -- but needs to tie off loose ends. (Portland has lots of Buddhist temples and stuff so none of this is all that surprising). In the meantime, the opportunity to enjoy your company would be fantastic, Fluent Python a great topic! So if another Pythonista pipes up with a confirmed location, please do accept. I don't want to leave things pending longer than necessary. About me: I work with O'Reilly School of Technology as a Python Mentor. I deal with hundreds of Python questions and exercises every week. I'm very interested in fluency, improving mine, improving theirs.
