Advanced Python Series - Iterators Vs Generators

[@PratikDalvi-mg8qx]

Yes..! I got the real Krish who helps the needy Students .❤☺

[@thalanayarswaminathansaipr7703]

Excellent! One additional point a function can have many yield statements however, we can have only one return statement.

[@lepidoptera9337]

Huh???? Where did you get this nonsense from? A function can have an arbitrary number of return statements. Multiple returns are functionally completely equivalent to a case statement or a series of if-then-else statements. A function can even have zero return statements. A function doesn't have to return a value. A function doesn't even have to finish. That's quite useful in multitasking systems that have to repeat the same functionality over and over again in the background.

nums = [i*i for i in [1,2,3,4,5]] for i in nums: print (i)

[@sarikavaidya6681]

You explained in very very simple and understanding manner ... thanks for making it

[@tirthasg]

Really? I found it to be quite confusing!

[@ramarao_amara]

other than generator function , we can use generator comprehension also used for creating generators.

[@AshisRaj]

10:33 crux is here

[@scortexfire]

8:40 def square(n): for i in range(n): return n**2 square(3) >>> 9 I'm getting 9 instead of 0. Why so?

[@shaiksalman9010]

in return put return i**2

[@pokejishnu]

Wow this was much needed Krish sir. Thanks a lot

[@shailajadavangave45]

Hi Krishna , before gng for interview i hv gone through ur iterator vidoe and same concept asked in interview as i hv gone through ur iterator video i was able to explain well with an example of iterator.iterviewr was very much convenienced with the example and answer .Thanks for the amazing video very well explained. I am grateful to you for these videos and easy explanation

[@lepidoptera9337]

As an interviewer I would have rejected you on your lack of communication skills alone. Life is not a series of smartphone texts. :-)

[@bongmou2845]

Thank you for the clarification , well explained .

[@abhi9029]

superb lecture Krish.

[@shahnawazkhan1636]

Amazing krish

[@pratyushbehere3580]

Still don't understand where this will be used

[@abhi739]

Thanks Krish, very good explanation

[@ranjit9427]

Why is Iterator more memory efficient compared to the Generator??

[@prannoyroy5312]

It is the other way round. Generators are memory-efficient ways of processing huge datasets. They process the data incrementally and do not allocate memory to all the results at the same time.

I bought the membership but I didn't received the study material

[@animeshmishra4282]

Best video needed it so much. Thankyou sir.🌟

[@nashrahrahman3547]

Sir, can you please make a video on decorators as well ??

[@masterhipster8358]

Plz tell if im wrong sir, In your 2 point yield save the local variable value. I think Yield hold the state of local variable.

[@narangfamily7668]

Wonderful! Thank you so much.

[@donfeto7636]

Think about it generator is like yield return in c# which just return a list which you can iterate over it , multiple return rather than 1 return value

[@kartiksharma-yw7qf]

Sir any update about data science 15 month course by ineuron?

[@melodyofsoul4933]

I'm getting this error AttributeError: module 'collections' has no attribute 'Iterator' while calling this function issubclass(types.GeneratorType,collections.Iterator).

[@sgn1989]

issubclass(types.GeneratorType, collections.abc.Iterator) should work

[@saleemmohammad8986]

Well explained Thanks

[@rajinigd]

sir i have a query can you please share how to use the log values for a set of values in column

[@shrinivas1086]

for i in range(3): here "i" which will iterate through the range values. can we call that "i" as "iterator"? if not why?

[@helovesdata8483]

No because I doesn't iterate through the range of values. i represents each individual value in the range from 0 to 2.

[@vikinist]

Why not we do the same task with functions

[@hassanhijazi4757]

As the 4th point, I think you mean the opposite, right?

[@SigmaSid98]

One small correction: Generators are more memory efficient than iterators in python.

[@abhinavlakhani5637]

It looks like Iterators are using "linked lists" under the hood.🤔

[@AnilKumar-do6nj]

Hi this is anil how to read directly excel sheet wise data without download excel file s3 bucket using python please explan

[@AnilKumar-do6nj]

Thanks

[@KairanaExpressIn]

I want to learn python in hy head, first learn html first or c language Please Reply

[@mdmamun-vp9xj]

First viewer😘😍😍

[@chinujaglan5782]

ohhh

[@amitsingh-ox4uo]

Didn't make any sense.Where is it used?

[@MuhammadShahzad-dx5je]

#awesome

[@swadhikarc7858]

Nice video krish. I can see the effort behind making people to understand 🫡

[@navneetshrvstv507]

Generator is memory efficient not iterator

[@chinujaglan5782]

i was thinking i would be 1 st comment 1 like 1 view but in 18 second 18 view and 7 likes

[@sampleraja8026]

He has to know the difference and it's application. Video is not worth.

[@abhidawkhar5105]

Too many adds

[@gouravnandy5401]

Not a good way of teaching. Doesn't make any sense
