In pycharm you can use (control + d) to copy the line and paste it onto the next in the place of using (ctrl + c) and (ctrl + v).

print(next(values)) prints 1 and also changes the state of the iterator after which num = 2. So the for loop will print the numbers from 2 to 10.

The raise keyword is used to raise an exception. You can define what kind of error to raise(here its StopIteration).

Sir, when will you make videos on tikinter and other python GUI?

Excellent tutorial 👍👍

whether during the creation of the object itself __iter__() method is called just like __init__() method? Is __iter__() method is called only once?

What happens if we print(next(it)) beyond the range of list? I mean what if we use print statement 6 time if the list has only 5 values? And can we access the index of an element using iter() and next()?

I really Want to thank you Navin Sir..My college faculty never focus on the concepts of programming they are just making us rattutota... Thank you so much sir for coming on youtube and helping the students

omg you are a true programmer :D i lauoh so hard when the output print None. i like you debuging method

sir can you put another vedio on this. i dint understand completely.

I just debug and found how that statement for i in values just calls the next function in Topten class , every time after printing the value of i . This is awesome . You should include a debug session in this video itself.

very interesting and knowledgeable tutorial.👌👍

Brilliant, thanks a lot!

Dil se dhanywaad🙏✌️🤗

this we can use for interview question but for loop is the best. I haven't used this loop in my entire life

In if condition can we use break to stop the iteration 9:33

This was exactly what I needed thank you

if I use exit() instead of Raise Iteration then what problem would I face?

Thank you Mr. Navin !

Sir, Why can't we use break in else part to stop the execution of for loop ?

"try and except" also could be used right? Was there any reason that stopped you to use "try and except" ?

What is going on behind for loop it is good,,,, but what is the use of iterator

sir what is the advantage of iterator over for loop

I like your learning style

is there any way of using variable in place of self.num = 1 means self.num = n and then iterate it for 10 times

wow you really explain well and are one of the few indians that have no accent almost respect

and instead of giving exception in else part can we give break statement at the end of if statement?

ಸರ್...ನಿಮ್ಮ teaching ನನಗೆ ಬಹಳ ಇಷ್ಟ. ಈ videoಇಂದ ನನ್ನ ಎಲ್ಲಾ doubtಗಳು clear ಆದವು. ಧನ್ಯವಾದಗಳು. సర్...మీరు teaching నాకు చాలా ఇష్టం. ఈ video నుండి నా అన్ని doubtలు clear ఆయింది. ధన్యవాదలు. ಜೈ ಕರ್ನಾಟಕ (జై కర్నాటక)!! ಜೈ ಕನ್ನಡ (జై కన్నడ)!!

Nice mustache! It suits you Sir. :-)

concept is extremely good no doubt on that, but your new look does not matching with personality..... but really your teaching style is awesome, thank god that you are providing such valuable knowledge with free of cost...

Can someone or Navin tell me this that why are we not converting that TopTen class object 'values' to iterator object i.e like values = iter(values) As you are not creating iterator object in last example how is __iter__ method getting called or how is it working without it. As far as i know if we create an object of class only init method gets performed without calling. Please Help me with this. And Cheers to your work Navin. Thank you very much

sir after class python is becoming difficult any suggestion

I'm confused. Couldn't we just print "nums" to output the values? Why did we need a "for" statement to display all 4 values?

Thank you Mr. Reddy!

hiii bro, create the own class that not repeat again values...but inbuild the value or nums it can repeating ....i wanna clear about it this video

Excellent video! Thank you

Hey if we have for loop to print 1 to 10 number, why should we use this iterator

sir can you let us know a real life example where we use iterator

Sir can u make video for machine learning usking sklearn lib for data science

Thanks 😊....

The when you say Iterators. How cool is that..

If you type print(next(values)) after the for loop, you will get an Error.

Sir what if want user input??

If something is returned in a function it return value to function call right ? What is happening to return here. Object is being returned......

Sir can you please create video on data structure and algorithm

what is the use of- values=toptens ?

Navin, pls stat what is the purpose of __iter__ method at all

By this way are v overloading the Iter & next inbuilt function ?

sir why are we using raise ? can we not use break

Sir, can we use limiter in __next__

Under the def __iter__() method, why are we returning self only? And what does he mean by 'returning the object' when using this method? It's just a self keyword with no parameters. What does this mean? Please help

at 5:11, why did the for loop print 7 and 8 again? this contradicts with 10:22 no?

Sir, My Final Year Project is on Virtual Mouse using Hand gestures using OpenCV and Python,Can you please help me in this,Sir?

sir could you please suggest me a source from where i can practice python, please!!

how to goto previous element in interator?

Thank you

First view! For the first time.

since we already have for loop to iterate the list then why are we making things more complex by making this iterator

can we use break instead of "raise stop iteration"

Good sir ji👍👍👍

sir!!!! in the before example u have shown the repeation of values getting in output...but in this example why it is not repaeting 1 and taking next values......

If you want to work the loop for multiple times put "self.num = 1" in else condition.

Nice!

Finally I got this yayyyyy

'1' will be printed twice as the 'for loop' always starts from the 1st element in the list. so both are different things and it will give the twice ones then will continue up to what we want to print.

❤. O/P: Same

Sir, Pune MeetUp when....???

What is the use of iterator while we have a for loop and we can go for a every element of the list....

Sir, please make on video of game development and app development.

Sir the video is a little bit confusing regarding creating an our own object of iterator My doubt is initial part of video we created our own iterator object that is it,then what is the difference

what is the use i dint understand when u want to print one by one it is done in 1st example bt in 2ns e ample own iterator all numbers are printed at once not as u told one by one dint understand what’s the real use u want to tell sir

Sir other way to stop the loop is self.num=self.num+0 , is this right sir

one more video on iterator please

Sir, At last when we call print values then we should two ones because of init function and other one is because of iter function but we are getting only one value of 1. I am not understanding this can you help me in this.

sir how to do text parsing in python?

Why only return self is use under iter block

Where are we calling next function in for loop and without calling it how the value are printing??

It's very funny when you said to NONE iteration "eehh HOLD on"

What does that __iter__() method do here sir

It will print 1 or 11?

Can someone help me know that what happens after "for i in values " is called ?

It will be very very gladful if you give sometime in answering the good questions asked by us. Because we get into some confusion whose answers are not available on google. Then we got stucked there. So please at least give us any opportunity to get the confusion clear in between 2 days so that we will also don't lose the interest in clearing the questions. If you don't have that much time then you can also answer only necessary and tough questions.

Can u please tell the time complexity for the iterators

Sir, where have you learnt all this stuff . I am watching the whole series,your concepts are strong. Can you please tell me which course or way should I choose , For web development via. Python. I am cs student. 2nd yr

So why we use loop if we have iterators

Sire, in object creation we have created __iter__ function but we didn't called to make that object as iterator. Then how does it work???

what is the use of __init__(self)? why cant we simply use val and increment values to it?

How we typed self.num and we hadn't typed method named num or class nemed num?..num is not defined..

Can we use break instead of raising exception?

break also possible

PCAP Certification?

after a long time i have seen your mustache

Why do we need the iter() method while defining our own iterator???

hi sir,I don't have IT background ,completed B.Sc. Zoology in 2013, now keen to join IT field,so can I start my career in Python ? Are jobs available for fresher Python Developer in market? Could you please guide?

modified iterators form where to start and where to stop: class ur_choice: def __init__(self, num): self.nums = int(input('enter from where to start')) def __iter__(self): return self def __next__(self): if self.nums

print statement prints 1 and the for loop prints 2, 3, 4,..., 10

sir i have a question Why u used " raise StopIteration " ? why not u use " Break " instead ??? please explain anyone

It prints 1to10 but if we remove for loop it will give you only one

There was an indentation error at return val thats why its repeating., remove 1 space before return.

nice video
