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

What is the Python interpreter and how does Python work internally?
In this video, I talk about how the Python interpreter works and how it runs your Python source code. Essentially, the Python interpreter is comprised of two subsystems:
1- A compiler: this compiles your source code into an intermediate code called the 'byte code'
2- A Python virtual machine (PVM): this interprets and executes the byte code on your machine.
A good understanding of the concepts discussed in this video is crucial if you want to master the Python programming language.

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

[@steveq1881]

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

[@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.

[@ryezizzle]

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

[@aryandugar9810]

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

[@ColonelHathi]

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

[@SUPERHEAVYBOOSTER]

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

[@monazine]

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

[@averystehr]

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

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

[@estebangomez1823]

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

[@ItzRaiyan]

Brilliant Video! This was a very informative and detailed video

[@jordinp2140]

I needed this, Thanks! Really well done.

[@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!

[@gopesh97]

Amazing!!
Thank you so much for posting this.

[@uchihalayan3435]

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

[@HemanthKumardigital]

Thanks bro , for clear explination its really helps

[@sowmyaganiga4155]

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

[@navnitkumar138]

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

[@mosheglobus1124]

Thank you. High-quality content!

Hey Karim, that was really great thanks!

[@azertyman776]

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

[@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!

[@jeeveshvanga2598]

cool and clear explanation 🎉

[@guilhemescudero9114]

THANKS! Amazing work man!

Great explanation, thank you!

[@renanaoki714]

Now all make sense, thanks 👏👏👏👏👏👏👏

[@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.

[@umarbshehu7647]

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

[@zakriazaheen7616]

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

[@mujelsh9347]

Thank you brother. Great video Ya Mo3alem

[@tehDIMND]

thx man, awesome explanation :)

[@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

[@terrencemasuku8909]

man that was so cool. keep it up

Thank you so much!!

[@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.

[@ericay4054]

It is incredibly useful! thanks :)

[@RaviRaj-je3rh]

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

[@halim_Ha]

damn this is amazing man

[@user-ym2nq1gu2u]

Thank you :)

[@tatyanatarasova6480]

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

[@thedoremaq]

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.

[@VinodMoorkoth]

Subscribed !

[@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..

[@mannp31]

Thanks bro

[@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?

[@salonisingh9171]

Amazing ❤️

[@Afternerd]

Thanks Saloni

[@css_prep_essay]

Awesome
