What is the Python Interpreter? (How does Python Work?)

[@sajalchuttani2519]

just devoted 4 hours today learning how the python interpreter works and this video just summarized it into a 15 min video . Nice explanation , love the way you just go about explaining the stuff on a digital white board instead of some fancy animation stuff (which ofc increases information quality) SUBSCRIBED

[@ryezizzle]

dude, i spent all day trying to figure this stuff out, and you explained it so well. subscribed!!!!

[@quitchiboo]

Late to the party, but pretty much instantly subscribed. Clear, to the point, minimalist yet highly effective visual aids.

[@umarbshehu7647]

Wow! You just saved a life here. Thanks a bunch. Is there a continuation of this video?? You stopped halfway.

[@404-DreamsNotFound]

This is the best python mechanism of action explanation I've seen on the internet

[@Bojan456]

Amazing video. I love the added details from your old job and how it helps you to understand the new one. Thanks for sharing.

[@androsp9105]

Thank you for explaining this.

[@Afternerd]

I appreciate it! Thank you!

[@skpallu2649]

Study help me

[@gd2860]

Im the type of person who has to learn it from a very high level first then, the rest should fall into place. This fills a lot of gaps that ive had in getting started with python. Im new to this but again, I need to see the big picture first. Im an old network guy who mastered networking years ago. Been shying away from network automation but its what's here now and literally in my face at the workplace. Excellent explanation. Well done!

[@aryandugar9810]

this was awesome. i have not seen content about such python concepts explained so well!

[@karimamri4831]

You brought honor to our name in explaining the concepts well, good job! and thank you!

[@CadPixel-why-not2455]

great explanation , everyone says python is an interpreted language line by line but this vid says it all , thanks

[@steveq1881]

I've been searching for this info everywhere! Thank you so much for going into the details of how it really works.

[@averystehr]

Thank you so much! Well said! I've been trying to find this exact information.

[@PhamLinh-u3z]

Your way of explaining things is really clear and easy to understand! Thank you so much

[@ColonelHathi]

This the best video explaining how an interpreter works. Thank you for giving details and examples, not hand waving magic! 😊

[@danbromberg]

Excellent under-the-hood- description of what's going on!

[@Fb-uv4jj]

came here from your website. i think that you explain simple because you know subjects well. useful for me. high quality content.

[@Afternerd]

Thanks!

[@jetbob309]

I like your style of delivery! Id definitely buy a course from you! Thanks for the video

[@linguaphile24]

This is so clear and informative i like to know whats going on to understand later how things work even if i wont go deep to these codes. Thank you for this

[@ben_jammin242]

I was hoping this video was going to explain the actual parsing of the python code into the execution model, defines, declares/variables, function calls. Lovely video though. Thanks for the explanation. It was extremely thorough and concise - you definitely seem to take the time to really understand things. Would love to see more content by you :). Great personality too. ❤ Edit: syntax tree I think is the terminology I was missing above

[@SUPERHEAVYBOOSTER]

This was awesome. Thank you so much. It's so rare to find channels that really dig in deep!

[@Aksinia1599]

This is so enlightening! I have been looking for such explanation. Thank you very much for the video.

[@AdrianCortes-b7f]

I love that you said that ones and zeroes are just voltages on transistor

[@estebangomez1823]

This nailed it!!! Happy to found this channel!

[@MAYANKKUMAR-vm3gy]

Awesome extremely clear explanation, quick fix of basic python confusion..

[@lucascerveracom]

Great explanation! Thanks for sharing your knowledge in such an easy to understand way

[@RaviRaj-je3rh]

Karim bro😎...Truely useful content & logically presented .... 🐅

[@Afternerd]

Ravi! Thanks my man!

[@brady1045]

Well explained and super helpful, thank you!!

[@ahmed51988]

A very nice in-depth yet simple explanation

[@WaldoTheWombat]

Thank you Karim, excellent video! Why do interpreters convert source code to machine code one row at a time unlike compliers that convert the entire file all at once and what is the consequence of this difference?

[@merrymouse2008]

Wonderful video! You explain it so nicely and it is easy and interesting to follow. thank you so much for making it!

[@MagicM2024]

Nice done. Thank you for this great and easy to catch tutorial

[@sowmyaganiga4155]

Thanks for the information this is what needed to start with anything in IT , Please make more and more videos on basics

[@thedoremaq]

Thanks!

[@UnleashedEntomber]

Well, it's the best explanation on the internet, what can I say. Great job!

[@milton7285]

Thanks for a simple video. Keep it simple!

[@navnitkumar138]

Nice Explanation. Very impressive tutorial for me. Now I learnt How Interpreter works. Thanks a lot..!

[@uchihalayan3435]

this is the best explanation for the interpreter thank you so much

[@Nidza11q]

Great stuff,so easy to follow and understand.It helps us,beginners,a lot!!

[@prateeksharma962]

Great Video. Seen others, but this is the best explanation that I have come across. Thank you, you have strengthen my understanding.

[@MohyDev]

Hey Karim, that was really great thanks!

[@gianireyes405]

Man, this is pure gold. I've been many time asking myself and looking for this information, and finally I got a good explanation. Thanks, really. Aaaaaand I have a question if u don't mind: When you talk about the "memory" , you mean the memory unit in the processor, or something else ?

[@Afternerd]

I am happy to know that someone “cares” about this level of detail :). Thanks for your kind words. And yes, you are right, I am talking about the RAM that comes with your desktop/laptop. It is not really “in” the processor but it is connected to the processor. A processor has a component called a memory management unit (MMU) but this is not what I am talking about. I am talking about the actual RAM.

[@mosheglobus1124]

Thank you. High-quality content!

[@szhang2097]

I always like this type videos. Excellent and thanks

[@subhashgn1775]

Very well explained....👌👌 Thank you..🤝

[@madhanrajmoorthy8843]

Hi Bro, It's amazing way you have explained. I was expecting in my mind to learn like this. Since, the understanding of hard part will be reduced when we learn using basics with super diagrams. Hats off bro. Thank you so much. :)

[@Afternerd]

Glad you found it useful! Thank you.

[@aryamick]

Thanks a lot, bro!! That was indeed both insightful and easy to understand.

[@gopesh97]

Amazing!! Thank you so much for posting this.

[@YesuSira]

Thank you, this was basic and explained in easy-to-digest bites.

[@hanan_almulla]

finally a great explanation!! thanks a lot :)

[@johnkunz7798]

This is such an awesome explanation. I've watched and read stuff on the GIL and how it regulates threads. Please explain this and how this somehow works optimally for IO operations.

[@azertyman776]

Nice video ! It helped me a lot, keep going !

[@ItzRaiyan]

Brilliant Video! This was a very informative and detailed video

[@promechafox8083]

What an Amazing video. Very Easy to understand : )

[@jordinp2140]

I needed this, Thanks! Really well done.

[@yusupovjasur]

Great in-depth tutorial, thank you!

[@soulelemanator97]

This was so helpful and well said

[@davidkuda7074]

that was very informative, thank you so much for doing this!

[@jeeveshvanga2598]

cool and clear explanation 🎉

[@fentazimohamedreadh5274]

Thank you for making this video. I managed to understand it clearly (though I have a decentbackground in computer science). But I'm sure even a beginner would understand modt of it. Make more of those thank you!

[@zakriazaheen7616]

I recommend sir lectures for very beginners so much friendly and easy .

[@utkarshujwal3286]

Thank you so much. It clarified a lot of my doubts.

[@renanaoki714]

Now all make sense, thanks 👏👏👏👏👏👏👏

[@hemalakshmi1187]

your teaching was amazing and thankyou so much

[@HemanthKumardigital]

Thanks bro , for clear explination its really helps

[@barjammar]

Thanks. I agree with you that understanding stuff is easier than just learning and remembering. I'm also looking for a lesson on what all the windows are in PyCharm. How do I get rid of them or use them. Also, point a particular window at the file in use rather than the file I was using yesterday!

[@akari.creates]

Likewise..

[@terrencemasuku8909]

man that was so cool. keep it up

[@LC-sx2ht]

Great explanation, thank you!

[@blandon93]

.pyc is some kind of assembler-like program. instruction 1 is write to a memory adress. q is how does it know where to write, I guess python takes some portion of ram when you run the interface, or OS give the adresses.

[@hisstoryinthemaking613]

excellent work explaining this.. very practical 🙂👌🏽

[@rajarsiroy6362]

Great explanation, thanks

[@guilhemescudero9114]

THANKS! Amazing work man!

[@zui0per342]

Started learning python today, i wonder why there are not that many people here

[@tatyanatarasova6480]

I'm a nerd! )) couldn't stop asking myself how it works. Thank you!

[@celestial2091]

Amazing video!!

[@mujelsh9347]

Thank you brother. Great video Ya Mo3alem

[@tehDIMND]

thx man, awesome explanation :)

[@qusirramzan3497]

Hi, dear can you please explain that why we get error while run this instruction 2**2 in Python Terminal (VS Code) [Error: You must provide a value expression following the '*' operator]

[@Mike-og4wc]

Great video, thanks a lot!

[@personsname0]

Great explanation!

[@nabanitabarik4419]

Thanks man. 👍 It helps lot 😊

[@awusacollins]

Great explanation)

[@peek-aaa-boo758]

Helpful stuff 👏

[@mo7sin711]

I need help I'm studying the freecodecamp course, and when i type the following code for the conditional exercise x = 0 y = 10 if 0 == x: if y == 10: print('YES') the output in the VS code terminal is Syntax Error however when I run it in python itself or an online compiler, it runs successfully and prints YES I need help :(

[@VinodMoorkoth]

Great Video bro

[@yonahcitron226]

Really Great info

[@web_hub]

Thank you, sir ☺️💛

[@ricomajestic]

Do you recommend any books that go under the hood of python even deeper? That also go into why the language was designed the way it was, how and why it works the way it does, why it’s better than other languages, why it’s not, etc.

[@mayeganfriends6678]

I'm subscribing.....Gold information here

[@halim_Ha]

damn this is amazing man

[@mustgame2233]

wow. Great Job!!!

[@reccon_game]

Thank s this is very easy to understand

[@lxzhang4911]

Hi Sir, thanks a lot for the video. It's really very helpful. Still I have a doubt: if in the source code there are more than one statements e.g. 1). a=3, b=5; 2). c=a+b; 3). print c; Will all the statements be compiled into the byte code at one time and then dealed with PVM? Or the 1st statement will be compiled and handled by PVM, then the 2nd compiled and handled by PVM, then the 3rd compiled and handled by PVM?

[@Afternerd]

Great question! First off, this is an implementation detail. There are various Python implementations. In CPython (the canonical Python implementation), all source code statements will be compiled into byte code first, and then the PVM will fetch and execute the byte code one instruction at a time. There are some implementations however that use JIT for example which is closer to the first case that you described.

[@lxzhang4911]

@@Afternerd Yes I see in the wiki, there are several variations of interpreter. But I cannot understand them that clearly. Anyway thank you a lot for your video and your answer! It helps me a lot:)

[@matheuscerozi6649]

thank you, it helped me a lot

[@avikjis27]

Following the steps you mentioned, I didn't find the __pycache__(double underscored) folder created in my OSx machine. Any clue why? But if I use python 2 then it creates hello.pyc file in the same directory.

[@josemanueltrujillorodrigue1838]

What a great job!!!!

[@amarpreetkaur4477]

Where I can apply for job if I have only knowledge of 3 levels?

[@emaniftikhar4632]

So am I right that the memory stores programs and the CPU fetches those programs/instructions to execute them and hence produce an output ? Also why is python script mode and python shell are known as python interpreters?

[@Afternerd]

You are absolutely right!

[@emaniftikhar4632]

Thank-you

[@byroniniesta5370]

Thank you sir.👍

[@sosobel5220]

Please, is it possible to compile into java bite code than run the code under jvm which mean output a 100% java code.

[@herdenq]

It's certainly possible. You may need to write the compiler, though.
