Awesome video as an intermediate python developer I gained a lot of insight...one thing that annoyed the shit out of me is the use of the word “orientated” rather than “oriented.” I’m not crazy right? Isn’t it supposed to be oriented? Lol

I've got to say generators and decorators are very very useful
Albin Severinson (4 days ago)
Very interesting and succinct. This is the first time I feel like I understand the general ideas behind these concepts. Thanks.
Jimmy Dawson (4 days ago)
Around 10:00, he types def __repr__(self): return 'Polynomial(*{!r})'.format(self.coeffs) Can someone tell me what the *{!r} stands for. I'm know some of the basics of Python. I understand the { }, but not what's going on in and around it.

the whole talk went over my head, I did not appreciate it, it seems I am more a beginner than even I thought originally...
Julien Bongars (9 days ago)
This is incredible not because it dumps a bunch of technical lingo and just leaves but because it makes you think about how you can use these higher levels concepts in designing and enhancing good software. Awesome work!

The generator API example was exceptionally helpful. It was the perfect way to explain the coroutine pattern.

Those who are bashing this guy, if you can do better than him what make you watch the video at the first place. No human is perfect.

NinjaBunny9000 (1 month ago)
This guy’s smug attitude and smacks of the mouth make this unwatchable. Incredibly stressful and exclusive attitude. He’s more concerned with what Microsoft employees he’s impressing than he is delivering a quality presentation. This should be more about knowledge transfer than ego...

i kinda get what he means here atleast the first one a bit because im bad at polynomials you know eeeh so kinda dont understand.

There's a level of arrogance about him that made this very difficult to watch. Case in point at 20:20 after subtle other glares and "i'm pretty good" moments and begins a mini-tirade about the thankless task of engineers who build for others (which is always the case anyway), but that you're furthest from the action.. is pretty bloody cocky. He's essentially referring to the same individuals and teams who tirelessly build, say, deep-neural networks for the betterment of the business and in many cases the public broadly. So, building and powering the backbone of tools for others is no less important and if anything definitely less thanked. Turd.

what does it take to be an expert at python: 1) uninstall python, 2) install a language you can make money with, 3) profit
ragtop63 (2 months ago)
Another Python "Expert" using bs math functions to demonstrate non-real-world examples of how to use Python. Please do something useful and write something that someone would actually use. Perhaps, how to build a library to parse/modify an EBML header from scratch. THAT would be useful.

Gospel of Christ (2 months ago)
The 'Good News', Gospel of Salvation [1 Cor. 15:3-4] "I believe, how, Christ died for our sins, that He was buried and that He rose again the third day, amen." Watch the video. http://j.mp/2CUY2s6 Give Christ a chance, believe the gospel, be born again, repent and go back to Heaven. If you do not like Christ's program there, then you can always leave. You have nothing to lose, but everything to gain..

I wouldn't rely on Python with all projects & coorporation dependencies. Because Python is supporting by Google for their jobs and someday they may cut supports.

In all honesty I couldn't make it through the whole video. The problem shown is very ad-hoc and is perhaps how they deal with that very specific situation within the Company. However it has nothing to do with Python expertise in overall. The reason you won't see metaclasses used very often has nothing to do with it considered "magic", very hard, or told at certain moment never to employ these. It's mostly because metaclasses have very narrow use-case scenarios and unnecessarily obscure things. Python philosophy is very liberal to choosing a strategy in solving various problems. However it encourages a programmer to keep things sparse and transparent. As for the problem discussed in the first half of the video I am yet to see a library that would prematurely enforce user's code consistency. Its user sole responsibility to test if the code fulfills library requirements. If such a problem only manifests at the code presentation that means they never bothered to write any unit-tests or at least do some test runs beforehand. Why its ad-hoc and not commonplace? In example, lib user may not have all the required methods on hand but rather creates these at runtime based on their program logic. That isn't even an esoteric thing to do in Python. How would you catch this scenario properly ahead of time? I am not saying it's a bad thing to know these techniques I am trying to say that narrow thinking isn't what defines a python expert.
