I'm just a beginner to Python but still it was soo clear to me. Thank You for explaining it soo easily

[@helpingprogramming134]

Great Explanation now everything is clear, and we can also check reference no by using id(lst1) and id(lst2) it show the reference number. 🙂👍

[@ivansaiji]

I feel you could have shown visuals on the memory allocation for the nested lists part.
The whole point as I inferred from your video is that if you have a shallow copy it will allocate space in memory for two lists but the lists will be pointing to the same items, whereas if you do it with a deep copy then new objects will be created and that's why they will be independent like that. Am I right?
I just think you didn't stress this point as well as you could have.

[@DhavalAhir10]

In Python 1000 Same List Create 1000 new Memory location... Python can't take risk with mutable objects.

[@zahidakitchentreats9719]

Hello Krish, I think the whole concept relies on the following points.
= -> in 1d or 2d creates an object of the same memory location. Changes reflect
list.copy() in 1d -> copies the value into new object. Changes do not reflect
list.copy() in 2d -> copies the object in a object into new object. Changes reflect
copy.deepcopy and copy.copy() works for 2d only.
copy.deepcopy() -> Creates new object and inserts copy of the objects. Changes do not reflect
copy.copy() - > Creates new object and inserts the original objects. Changes reflect
In short, we need to see if we are putting copy/original objects.

[@chillmathematician3303]

this 12 minutes is better than 2 hours lecturer

[@abdelrhmandameen2215]

Absolutely

[@saikrishnavadali05]

[@nikhilkothiyal]

Sir can we call the copy (using assignment operator),a shallow copy

[@gurubalavigneshnatarajan3817]

Great explanation, now I am clear with the topic of shallow and deep copy . Thank you so much 🙏

[@ZahidHasan-cc8tf]

Sir, could you please do complete nosql course series from intermediate to advanced?

[@gouverneur2001]

goodmorning sir

[@dashingagg1]

Thanks a lot bhai. ye shallow copy aur deepcopy ka concept hi smjh nai aa raha tha bht time se.

[@noco04TheGamer]

Thank you for explaining it so easily!

[@mayflowerlily5326]

Hi Krish your channel is very helpful for all DS aspirants like me. Request you to make a video on the system configurations needed for deep learning projects and is it better to buy system or assemble myself as buying a laptop is out of my budget. I am looking to buy a system for my deep.learning projects. Thank you

[@raneshmitra8156]

Fabulous explanation of a very complicated topic of Python....

[@adityamathur2284]

Very nice explanation, I was confused but this video helps a lot! Thanks😊

[@Gayathri-i5p]

Summary:
1a) Deep copy: multiple 1 to 1 relationships from variable to memory.
1b) Shallow Copy: many-to-one relationships from variables to memory.
2) In a normal list, shallow copy behaves as deep copy whereas in a nested list, shallow copy doesn't behave as deep copy.

[@bhaskarg8438]

Your are Great !! helping the community

[@gtsui87]

This was a great explanation it was very clear. However, is it possible to add an example of when you would use either shallow copy or deep copy. I'm not sure when these things would get used.

[@mohammadazad8350]

I had a nested list which I wanted to copy using "=" and it didn't work, so deep copy is useful, however I can also make a loop that does the same thing

[@ezzsnippet125]

[@ravimody5536]

Does this even apply to dataframes?

[@rohitpant6473]

keep it up

[@mohammadazad8350]

I always thought python had "deep copy" set by default since it worked with non iterables but then I encountered a strange bug which brought me here

[@abcdeftanutanu2187]

nice

[@akhilsartnation9262]

maza aagaya bhai

[@tashinahamed7822]
