Hello, sorry to put this comment here but i need help with my flask app, im trying to put my app in an Ubuntu server but im using plesk, i already followed your instructions in your video about It but It doesnt work, this is my first website so im clueless and i would really appreciate some help

The more I learn the more I realize I know nothing lol. Keep up the content. Few channels that gets me listening to tutorial videos in my spare time just for fun lol.

The more you learn, the more you can assist others, keep learning new things. A secret, replicate all the content you are trying to learn, you will understand in a more easy way.

I love your content Tim. Keep it up. I have really learnt alot from you. I see as you as my role model

So excited to watch this!!

Keep it up Tim! Very very high quality video.

Thank you very much! Truly enlightening!

Tech With Tim I love your informative videos!

cool information thank you ❤❤

7.18 using '_' single underscore represents protected item not private, "__" this is private.

Nice can you also cover descriptors and Enums in detail they improve on dataclass.

Thank you bro

15:41 how do you type/ make those lines in the comment? Super clean. Love all your videos Tim, you have a gift for teaching

I like functool's total_ordering decorator.

Loved the video, but with all due respect: there is an error in the Fibonacci code. For initial conditions it should be if n < 2, return 1 (not n, as it will return 0 for n=0, but fibonacci(0) should be 1)

It all depends on how you want to start the fibonacci series. Series can either start with (0,1) or (1,1) or (1,2), all of them lead to same sequence starting at different positions. And the time complexity barely changes.

Nice video. It enhances my belief that freshers should start with C++ or Java. Understanding the decorator, design patterns, static vs class methods, access control, and other OOP concepts makes people write better Python code. Starting with Python should only work for non-IT who need to function quickly.

You are right. I feel in school or college, people should really try to learn: C to learn how a computer actually works Java to really understand OOP, Generics, Reflection etc. And C++ to implement concepts learnt from C and Java to create performant software

The functools cache speeding up the Fibonacci func is crazy. I know how it works but it's still crazy to see.

Nice video bro 😊

This cache decorator!

May we use setter/getter in django? Probably yes? If using models can this be used? Maybe as custom validators probably? My brain just wrote this out lol but seems feasible?

what do you mean getters/setter? property and property().setter, yes, but if you're writing methods called set_radius(self, radius) or get_radius(self), then no. Never. It's not java.

omg, I was on a NASA code project and it was full of: space_craft . get_intrument() . get_sensor . get_channel() . get_shelves() . get_shelf() . get_temperature() (and setters like that!) calls, and the 1st thing I did was turn it all in to @property and dunder getattr / init magic, (they were doing bare init class with post attribute setters), oh, and they had one class per module...so they came in Monday freaking out "85% of the code base is gone!" I raised my hand and said "you're welcome". It was pretty rocky after that ;-)

[9:02] zero is not a positive number, it is a neutral number, you should improve the ‘if’ statement, nice video 👋

Awsome 🎉🎉❤

Why do we use decorator? @4:31 mark? We could simply write another function and call the example function from within it. Add start_time and end_time above and below the function call to example function. Thatbwould be sufficient, isnit not so?

@rupen42

13 күн бұрын

Yes, that is sufficient _in this case_. But what if you want to time 5 functions? 20 functions? 100 functions? You can write 1 decorator and apply it to them all or write n individual functions for all of them.

plz make a pygame full course video

9:31 What would happen if we try to assign some value to c.diameter?

Error - no setter defined.

and if you do have the bad habit of assigning attributes outside of dunder init, you can use the setter to flag when it happens, so you can find the inevitable bug caused by that bad habit.

Ok, we've got python decorators - but when are we getting python painters?

Tim is da python expert. I'm afraid of pythons.

someone can give me more examples of when dataclass will be more useful than normal classes?

@DrDeuteron

25 күн бұрын

for me, when I'm reading 545 data fields of space craft telemetry, which is a helluva dunder init. Instead I just cut and paste the attributes from an excel file into a data class and it calls for a single mouse click. Moreover, dataclass comes with "fields", which can be used to describe the fields, the LaTex formulas for them. expected ranges, alarm ranges, broke ranges, and there is an astuple functions, which can be stuck in dunder iter, possible zip with the fields, and in about 3 lines of executable code, you can flag out-of-range telemetry. Very little dynamic code, and lots of static could is much simpler and less bug prone.

0:17 function, method or class

Which programming language doesn't support access modifiers these days? Do you think a convention stops people from wrongly using the methods or properties? Besides Python also doesn't support Interfaces. I'm not sure what's all the fuss about. Even modern PHP is more standard than Python; which people advertise PHP is dead.

@rupen42

Python is a language for consenting adults. Not sure what you mean by not supporting interfaces, since untyped Python obviously doesn't have them, and type-annotated Python definitely has them (protocols). There are also abcs (abstract base classes) that serve a similar function _and_ are checked at runtime.

I think the rocket scientist that thought about how or why to create decorators were drunked sailores full time, programmers part time.

Of course you’d never write a recursive Fibonacci function like that - you’d get it to return the last two numbers so you only need one recursive call.

@DrDeuteron

too clever.

So you implement privatization schema to 'fix' the deficiency of Python in having all public attributes and methods. Also adding 'hints' to variable definitions to make up for the type-agnostic nature of the language. Next "awesome best language ever" coming soon to a computer near you!

@Nova32x

Not really sure what you're point is. The main use case of the property abstraction of a private variable is for libraries. No reason for actual strict access control. Also type hints are mostly for runtime type checking and editors.

Just googled !r, it returns the repr in an f-string! And !s will give you dunder str. I had no idea this was a thing! Learned something new today.
