Broooo you just go a sub
Thanks bro
If you care about speed, don't use python(or Java or C#)
At 1:31 you put 10000 into the list comprehension, one reason it is that much faster
Yes, fair point. I had to do it many times to make the numbers be interesting in the video, but the point remains that this and all the techniques in total make a big difference in speed.
great, thanks
You are welcome! Thanks for watching!!
this is a very good explanation! Thank you! i finally understand it
I'm glad it helped! Thanks for watching!
Thanks a lot
Glad it helped! Thanks for watching!
funny how this doesn't need a new operator in other languages but python decided to be different
Would never ever think to write ls > filename
I have an even faster method. Ask llm
that works too!
Quit trying to make Python look appealing... It'll never work 😭😭
You jobless bro?
You can also add __dict__ to slots and get the best of both worlds.
Using slots also blocks __weakref__, but if you are inheriting from another class, than the parent classes must all also use slots to get the benefits of saving on weakref and dict.
and slower
I just dropped this video on making Python perform better: ruclips.net/video/cEe9_F0Sh4o/видео.html
python is heading towards tesla road with automatic, autonomous selfdriving cars.. It is getting way to abstract to the point it becomes useless... I want control over some basic things and I cannot design precise systems relying on abstraction!
How much long to publish new lessons?
I did 5 lessons before, they did not do well, so I stopped. I might start again if I can get views, and if I can create content people want to see. In the meantime, here is the next video ruclips.net/video/QHF1uxBrXp4/видео.html
Thank you for this video. when i see results of TU, they are all in red, like no tests has been executed. you know why ?
If everything's turning up red, it could be because JaCoCo isn't detecting your tests, so double-check that you're using the right annotations like @Test for JUnit. Also, make sure your build tool (like Maven or Gradle) has JaCoCo properly configured to run during the test phase.
lol this lib is literally just a “if you don’t know how to write a generator”lib
A for loop with extra steps. Cmon
i love you! mhuuuuuuaaa!<3
Well if you want lightning fast don't use python
Stay tuned, I have a long form dropping soon that discusses some ways to make Python perform better.
What does number = 1000 do in the argument
Run it 1000 times
@ximega5875 Oh, thanks 🙏🏻
or u can do it like this: from math import sqrt as s
When you grep "m" because peer review requests a more descriptive module name
Um vídeo muito porreiro pah, obrigado parceiro!
From math import * Will this allow us to get rid of adding any dot and m or math before that?
in that case, u’re telling python to import everything from the said module, aint a good practice
That’s very helpful!
I glad it helped! Thanks for watching!!
That’s neat! What about using them in order methods, you don’t need to prepend the attributes or methods with self?
Other methods behave the same as a regular class: you declare self in the method definition and use self. to access object variables
@@Danielagostinho21 thanks!
