your style of tutorials are very clear and concise with excellent explanations of how everything works. I watched just three of your videos and they have answered all of my questions about threading and multiproccessing with python. Thank you codebasics! Also, where is your Patreon link so that i may buy you a lunch?

just finished watching your multi threading and multiprocessing tutorials and i have to say.. you are the best!!!! u need atleast 100, 000 views for this kind of simple and well explained video. Thank you for all your hard work archiving these teachings online. i cant wait to get into your matplotlib tutorials! <3

[davidfazio]

Your explanation of multi processing, threading, and the differences between are excellent. Thank you for using general examples that are relatable as an introduction. This is exactly what I needed!

I am enjoying this tutorial very much from last 2 weeks. Dhaval sir, your style of teaching python with real life scenerios is very excellent. Now, i am able to relate python with my tasks in daily life.

Thanks for clearing these parallel processing, multithreading, multiprocessor concepts using python coding. Very easy to understand!

[dejohnam]

Thanks for the video! I've looked at the documentation for Pool several times, but your video was the first time it made sense. You explain things very well!

[josephbaron]

This is a great tutorial. I really like how you split things up into "bitesize" videos so that it's easy to find advice on exactly what you want to learn

[kathirangamuthu]

Thank you very much.
Multiprocessing pool PPT & coding is more informative.

[karthik-exdm]

Awesome man!!!
I actually ended up using multiprocessing in one of my projects... Saved me a lot of time
Keep it up! Good job

[sohamnavadiya]

[Nikkes]

Thank you for the tutorial series! I've been wanting to add Python to my programming toolbelt for a long time and you have helped enormously with that.

[VenkataRamaRajuLolabhattu]

very simple, calm, clean and great explanation.. Thank you

[moziahsanvicente]

thank you so much! i have been looking for the close and join methods. None of the examples I've found so far use these, and this was leading to a huge pileup of stale processes on my cpu.
