After almost 5 years, I keep coming back to this lecture for guidance. This is way better than any python course out there

His amount of knowledge, self-confidence and pedagogy explaining all kinds of concepts and scenarios is definitely worth of all my admiration as a developer. What a sublime guy he is.

It is not crazy for me to say that the first 20 minutes of this talk taught me more than every programming class I had before I saw this for the first time ...

I think this lecture is truly one of the kind because you rarely see any python videos talking about these very niche Python concepts. Plus, his style of presentation is great.

If only every talk on every it conference was as interesting and useful as this one.

James Powell for the President of Python please!

I can't believe how good this instructor is. This is a terrific live demo training course.

For the `__init_subclass__` definition at 46:51, you can do something like class Base: def foo(self): return self.bar() def __init_subclass__(cls) -> None: try: bar = getattr(cls, 'bar') if not callable(bar): raise TypeError("bad user class: 'bar' must be a callable method") except AttributeError: raise TypeError("bad user class: 'bar' method not found")

i think that currently to solve this kind of problems Id use ABC and abstractmethod decorator

This is one of the best live demo explanation of advance python concepts.. Really helpful stuff

great lecture and the approach to make the advanced topic so easy to understand.

What a great lecture

With the interleaving generator at 1:24:00, what does the client code actually look like? How does the user of this kind of generator function return control back to it, after the yields in-between first/second and second/third? Is this where next() and send() get used? Is there an idiomatic way to write the client side of a coroutine without next/send?

Just what this incredible person says about the books in the beggining is exactly what all us feel like

Great presentation! Advanced techniques but explained very clearly - that guy is good :)

references is the best here. I will always keep this as one of my best resources.

Вот молодец, ничего не скажешь. Синтакс побоку, главное правильный взгляд на вещи.

the best explanation of decorators i ve ever seen

Clear and well-executed lecture with illuminating examples, but I was still left with one big question - which is, how the hell do we have an access to this kind of stuff, free of charge.

very well presented. really liked it thanks.

yes his talks are eye opener for me . I never Enjoyed a python like Truely entertaining and gem of knowledge here . Powerhouse I should say :) Thanks to @James Powell for keeping talks interesting and Curios it really keep our brains Busy and focused when you deliver talk like this .

Where can we find more excellent lectures like this one??

1:25:00 The equivalence of context manager metaphore in Java is try with resources I think, and to use an object with tey-with-resources it should implement either the AutoClosable or Closable interfaces.

Still the best advanced python talk.

Actually, the code in 42:17 does not result in the desired behavior. Once we import Base in user.py, python finds no bar methods in the Base class and raises an error.

it's format syntax for conversion and tells the interpreter to format the string using the repr function, check here for more info: docs.python.org/3/library/string.html#format-string-syntax

I am a C++ dev, and seeing all the function details at runtime. WOW... I should move to python. LOL. Remember it has a cost associated with.

How strong typing would remove decorators, generators, overloading, etc? The only place it could do something - when he was talking about subclassing
