Python Tutorial: Iterators and Iterables - What Are They and How Do They Work?
HTML-код
- Опубликовано: 19 июн 2024
- In this Python Programming Tutorial, we will be learning about iterators and iterables. There is a lot of confusion around these terms and exactly what they mean. We're also going to learn how to make an object ourselves that is both an iterable and an iterator. This video isn't only about understanding these definitions. It's also about understanding the concepts of iterators so that you can write better code. Understanding these underlying concepts is going to help you write code that is more efficient and will also help you see solutions to certain problems in a way you might not have thought of before. So with that said, let's get started...

#Python
best python instructor ever
True
While True:
100% True
I couldn’t agree more.
HardCore my thoughts exactly!
These tutorials are epic, how can you talk 20mins without any single unnecessary word, truly amazing. Thank you so much Corey. You are my #1 Pyhton reference in my classes I teach in the collage! Keep up the great work!
practice
Thank you for making these awesome videos!! Goal after graduation: support your channel.
Did you by now :D
1. In Python, an object can be called an "iterable" if it has the dunder method __iter__ which should return an iterator and an iterator is an object that has the method __next__.
2. __iter__ is a method that a python list has.
3. By performing the for loop on the list, python invokes that list's __iter__ method which returns an iterator that we can loop over.
we can do next(mylist.__iter__()) which invokes the iterator's __next__ method or call or invoke it directly: mylist.__iter__().__next__()
we can also do next(iter(mylist))
"Generators are iterators as well, but the duder iter and duner next methods are created automatically."
Old but Gold. What an excellent explanation
Corey, you're awesome! You always make my day. Anytime I'm in need need of a lesson on any python topic, your channel is always my first port of call, to see if you have it. You always know how to make it sink in so well. Thanks
Corey Schafer ... U are the only Foreign RUclips, Instructor of Python whom i Follow. Your Videos contains information multifolds 10 which we get from any other video.. I am Surprised how do u do this...You make Sound Python Like Childs Play ... Hats off to u ... Expecting Machine Learning from You. That could be the Internet Breaker Videos of Yours
Corey, Thank you for explaining this so well and simple. I have been using both iterators and iterables for while, now it makes a lot of sense.
Thank you so much for the consistent videos and tutorials and the help that you provide for people new to this ^^
Dang it, I wanted to say FIRST! :)
You seriously teach this stuff better than anyone I've found. Thank you so much!
Precise, coherent, well articulated and well structured; good tutorial, thanks
Corey, Simply you are the best when it comes to making someone understand the concept. Unless someone understands the concept, it is very difficult to write codes that are lot efficient and at the same time very easy to understand/read. I wish everyone who makes video on programing follows a similar template for teaching. Thanks a lot.
You're the best instructor I ever had. Thanks for all your precious efforts it mean a lot.
dude.. your voice is so distinct and your explanation is crystal clear.
if I can't find something on StackOverflow or if I'm learning a new concept in python, your channel is THE resource for me. Great content.
Thank you for keeping it free.
Oh My God....I didn't know learning python can be this addictive.... Thank you sooooooooooooooo muchhhh
It really sums up the concepts in a concise but precise way.
Thank you a lot for this!
i've tried a lot of teachers in order to make progress and non of them works , you are the best sir i advise everyone want to learn python to watch your serie
You have a very clear teaching style - a very valuable talent to have!
OMG! Watching since last 4.5 hours, dont know when last I have wateched videos for so long. Addictive. Corey you must be a Teacher. Thanks for such nice videos
Ur videos are awesome Corey I have been watching all ur videos... please make an video on SYS module as well as XML parsing...I have got bunch of videos from you tube none other videos are up to the mark as u...ur explanation in any concept is at peeks no body beats u... thanks a lot
thank you so much for this video. I've been queering bing chat and bard chat for a couple of hours on the iterable and iterator topics but none of them managed to explain the stuff to me in a so clear way that you did.
One of the best explanations on iterators. Thanks a ton!
Thank you for this video. It is pretty clear and to-the-point. Well done.
You're definitely the best python instructor on RUclips by far...But some of us will appreciate it you could maximise the screen size we can clearly see instead of straining our eye which is probably not the best. Thank you
Thank you for such a profound explanation!
Excellent video. Thank you! You are my favorite programing(python) teacher.
very good explanation in this and generators video (also watched your other videos) - thanks to Corey
coming from old languages like Fortran, Cobol, Pascal and I just began learning python 3 months ago and this videos helped me a lot to get a basic knowledge
Thank you so much Corey, much appreciated how helpful this(these) videos are, just thank you 👍
Hi Corey, most of my doubt got clear through this channel . Thank u so much for this . I am suggesting two more topic please make a video on those.
1. Why Tuple is faster than List ?
2. Why List comprehension is faster than for loop?
Even after years, This is easy to understand and relevant, Thank you very much man
Thanks for the straightforward and non-verbose explanation!
Brilliant Corey: one of your best videos!
looks I found this bit late since this was published but trust me Your are the Best . I have gone through so many videos but the way you explain and demonstrate is AWESOME!! Keep it up :) All the best...
Closure and Decorator tutorial of yours was my first experience and I am telling you, you have explained it in such a good way that I cannot forget it ever. I am not being dramatic but your explanation method is magical. When I am learning any concept, there are things which are buried inside my mind and but it cannot get out because I feel confused and also nobody talking about the same or have that kind of explaining system as yours. It's like you are connected to my mind.
So, Thank You Very Much!! God Bless You!!
Thanks! Glad to hear that
Super, very useful lesson. Great stuff in a shortest possible time. Thanks a lot.
Excellent idea with the coding problems. You never really understand something until you have to use it!
Very plain and well explained. Thank you Corey, subbed.
Your lectures are amazing! Thank you so much for this!
Again, exactly what I was needing to clarify. Thanks.
Many thanks man! You are truly great at teaching! Please continue with this awesome work
My search ends here. Excellent explanation
Great Python Iterators and Iterables Tutorial. Thank You.
This video is amazing! Your teaching skills are top
Thank you, Sir. I wake up at 4 in the morning and continue watching your lessons.
Thanks a lot for the video, man it's very helpful to explain some vague ideas from some modules.
Thank you, man! Very clear and concise.
So python lists are singly linked lists! Awesome! Thanks for this and the tutorials on generators. I purchased a python book but it never delved into the material as deeply as what I wanted. Thanks.
Python lists are not linked lists
Wonderful teacher. Clear precise and best..
Just half done with the video and just want to say WOW!!! Corey, try writing your own python book.
Awesome content as always. Please make a video on asynchronous python programming!
Thanks a ton ... your way of teaching is one of the best , please keep on posting tutorials on pandas and Numpy or any advanced python topics , thanks

Great Tutorial.
Beautiful! Corey you da man!
thanks so much, great explaination
Simply the best!
Still being perfect explanation, there is still a need for preparation work to understand all the stuff Corey is explaining.
Hey Corey ! there you go . The best python instructor on RUclips ever . Kudos to your subject knowledge and teaching in an easy and understandable way . Expecting JavaScript tutorials from you too.
Had a long time issue in understanding this concept. You, Corey has always made easy to understand. Can you please make a series on selenium in python.
so what is iterator?
thank you very clear your explanation
Thank you.
Great video as always!
Btw, I think you meant 'generator' instead of 'iterator' at 20:12 when you talked about memory effeciency.
Love the idea of a password bruteforcer .
Please make a video on it
Corey you are the best.
Great explanation!!!
Thanks Corey!!
Best Python tutorial
From the time you mentioned the never ending generator and iterators not being able to be recalled it reminded me of a database auto-increment field.
Just waiting for the timeseries MatplotLib video.
He can make sense to even an absolute beginner, good
You are a king man!
finally i can try to understand why for loop is different from while loop. thanks
Great Tutorial
Classes in school should be like this a hyperlink to what you dont understand included. 💯
fantastic teacher
thank you for this amazing video i have seen lot of videos from sentdex but still sometimes i did not understand as compare to you explanation Thank you very much you are helping like us soon i l help you i m trying to freelance in python thank you :D
I used to listen to sentdex but after finding schafer, I found myself listening to schafer like 90% of the time. No hate to sentdex, tho. Subbed to both.
Great explanation
Proper good job mate.
Thanks Corey
Thank you , you’re the goat
this guy's a genius
thank you very much.
awesome explanation
Correction at 1:38 Corey said "Loops aren't the only thing that we can loop over " but he meant "Lists aren't the only thing that we can loop over "
gee thanks
