Òzbekcha variant yòqmi?
How does the computer execute a while loop in Python, and what are the steps involved in tracing its execution?
Depends on the language. Python here compiles to bytecode, makes a file which is run. After that it's interpreted line by line in runtime. Honestly, it's not usual to worry about any of that under the hood stuff. Especially with beginner level stuff like this. Enough to know there are a series of steps which take the code to machine language and ultimately binary instructions which become the fetch, execute cycle.
That's great

May God bless you for standing for humanity. I believe all students parents will soon join 💞✨
Brave beautiful people 🔥😛
Thanks you we proud of you all 💞✨
So proud of all you students! You make us proud. 🧡💖
Thank you keep going and unify with different university and raise your voice together and have leaders who can take this to another level you guys are young and strong and your voice is hard all over the world. You guys can bring changes keep going thank you. we are hopeful now that Palestine will be free soon. In shaa Allah. Also remember, we are all with you. 💖😘
God bless you, hero sisters. 😻👅
I am proud of these students risking everything for justice and human rights! ✨🍓
Thank you UAW 😘🍭
Freedom and justice for Palestine. ✨🍓
The younger generation of America gives me hope that the country isn’t entirely rotten. There are still people who care about humanity. May be we will have a better world for the remaining people of Palestine. 🇵🇸 💝🐱
Thank you for your hard work and for all the students in all the universities around the country. Free free 🇵🇸 🇵🇸 🇵🇸 🇵🇸 🇵🇸 🇵🇸 🇵🇸 🍭💝
We are with you 💋🔥
Respect for all this brave students 🧡💖
Our hearts with you 🍓🌺
I remember the Vietnam War protests that brought that particular corrupt disaster to a grinding halt..............keep doing what you are doing and thank you from an old man to the future leaders of our common humanity.......Carry on. 😘🍭
US also guilty of this genocide !! 🍒🧡
What animal do you suggest for friends? 💚🍓

Thanks for uploading 😊
TikTok brain again ✨🍓
What a load of Bull oney. 🌺💚
What grade is this for
Awesome ...Thank you 💞✨
are you protesting your universities that dont have anything to do with the war and not the military or government that make the decisions? You guys are way off in location 💖😘
Anyone on 2024?
Amazing lesson, thank you.
Thanks for making this, it is beneficial to research terms and gain a starting place to learn. I have a question though. Radiation = "no matter heat transfer". That appears factually not true, unless I am missing something. Radiation: energy that moves from one place to another that can be described as waves or particles. Please explain your definition.
The numbers may be imaginary but my confusion is 100% real
Wonderful 🤩
thank you Sal!
Where were all the women? I'm guessing there were not many women to choose from for all those young probably horny guys. They had a lot of pent-up energy.

I'm am just going to skip all my lectures and watch these.
This is so satisfying, I had no idea math could make sense haha
2:27 did bro jut figure out a secret code to dividing
Thank you for the help
Sir what if we consider the electric field of the electromagnetic wave is responsible for the ejection of electron instead of the imagining as photon like we did in reflection of light So higher the frequency the electric field wave the more the energy causes the of the light And thanks for this amazing explanation
Who is there before the exams?🤔
But how it become x+y+z=180°
The chemistry teacher gives me Walter White vibes
The notation used helps me a lot, and now it's clear what is going on. It's interesting how multiply a vector(in base B) with the C(change of basis matrix) results in a vector expressed on a standard basis. I thought the result vector was expressed in non-standard and led me to headcases
Thanks🎉
Would size be the same as measuerement? For example the measurement of the size of something would vary from miles, kilometers, inches/distance. But what about other measurements like temperature, mass, or volume. It already feels right to be adding those commas there. But for example using what you had in the video only changning "big" and "mower," it goes from "The cool big old square black Texan Leather riding mower." To "The cool 80-degree old square black Texan leather riding motorcycle." That feels right too, what is your opinion?
I can say he is a very good artist please reply ☺️
you are the best physics and chemistry teacher on the planet
