My friends and I don’t really get much from our Comp Sci teacher and try to use outside resources to keep A’s in the class. This video has single-handedly cleared up all of my confusion about for loops. Don’t know if you’ll see this, but thank you Mr. Sal from Khan Academy. You deserve every good thing that comes your way 💪

[@Pink_muffn]

It's astonishing to realize that this video dates back 12 years. Despite its age, he articulates the content with remarkable clarity and presentation. Kudos to you!

[@MAZaini93]

I've been trying to understand this for 2 days and my head couldn't wrap around the different variables and what they mean. You broke it down and explained it so well. Thank you so much!

[@tolulopetoluwade4116]

Hello, you're one of the best Python Instructors I have ever come across!!! Thanks for this video, so succinct and precise

[@Hp_359]

sup bro

[@F3EDER]

I got stuck in a tutorial understanding what the "for" statement does exactly and this really helped out not only to understand that but also how the loop works! Much appreciation!

[@Hype_Machine]

What are you doing in life now? Just curious if you became a programmer

[@TheRetiredBatman]

​@@Hype_Machineyeah i have the same question hahaha

[@TheRetiredBatman]

What are you doing now?

[@AlexanderMccarthey87]

This guy knows his stuff. I'm a lot farther than this, I'm just doing a review. He's emphasizing all of the important stuff that you need to know later. A lot of the other tutorials don't do that. Plus, he's doing it in such a way that you know everything you need to know and you can fully understand the concept. This is one of the best tutorials I've seen.

[@apprendredavantage]

I agree with your comment, He is the best

[@esadmusic6895]

i paid for a course and had to come here to get loops explained better and I was not disappointed thanks a lot.

[@cyber3572]

i absolutely love the way you explain things, easy to understand and step by step explaining everything logically so that anyone can understand, thank you.

[@shekharkumar1902]

None of youtubers explain for loop in such a simple and shober way! Amazing and kudos

[@Ben--Samsara]

So much clearer than the tutorials I've worked through. Thanks!

[@ruffraff3176]

Thanks very much for breaking this down. Doing a course online and could grasp what exactly happens with for loops. Much clearer now. Cheers

[@samsepiol5533]

First Khan Academy video and it's already helped me so much. Want to thank everyone who recommended these to me for my Comp Sci journey!

[@Phymacss]

I always had trouble understanding for loops, but it’s very easy now. Thanks a lot!!! Literally the best educational channel to exist. It teaches anything and everything!

[@Ezekiel_unabor]

Just wow wow. I want to say thank you again. Ive been trying to grasp the for loops for threee days now. And a ten minute video with you made me understand. Thank u so much ❤

What don't you know? It's remarkable how much you've helped me in college.

[@sangram361]

sir u r really great,finally i understand what is for loop at my age 30,before it was my mugged up concept,god bless u

[@remixowlz]

I Thank You from the bottom of my heart! My lecturer/tutor taught me multiple times about looping but nothing sank into my brain. Signed up for Online Courses and did not work as well! Not as detailed as your teaching! Sir thank you once again!!

[@cboyslim5490]

taking my intro to python in a zybooks based college class. everything was a well described (for the most part) process up til the chapter on loops. they worded it so stupidly, and the exercises are a joke or god mode programming on little instruction... i was panicking a bit until i got to your vid. thank you so much. makes more sense now . ez thumbs up n sub

Man I've been staring in front of monitor for 3 hours looking for this solutions. While all I have to do is open utube and watch ur video. Thankyou very much

For Python 3.6+ users: range (6) --> range (0,6) To get the list out type in ---> list (range (6)) range(0,8,2) --> range (0,8) To get the list out by 2 type in ---> list (range (0,8,2))

[@emmanuelleallen]

I saw that this video was 12 years old, and though "oh wow, this came out a long time ago, in the pioneer days of programming." But then i stopped to think how long ago 12 years was. And its onlt 2012. 😢 and I recognized the voice and the content style, and recognized i was on Kahn academy. I used Kahn academy for crash courses in my physics classes in highschool. Who knew id be coming back a decade later for any reason at all. Such a strange world we live in.

[@kylerollins6483]

+Mamawolfe I found what to do after doing a little digging: >>> for i in range(5): print(i) and then hit enter. I tried doing just range(0,6) and it just gave me (0,6). Didn't know if that's what you were referring to

[@TheGuyBehindY0u]

I have Python 3.3.2 btw My dad and I are trying to work it out (probably a bad Idea) I'm 12 and I'm intending to learn python to enter a competition where 12 - 18 year old kids have to write any program and the winner will get a prize, it is a mystery each year though :)

But still................................................................................ YOU AND YOUR EXPLANATIONS ARE AWESOME :):):):)

[@antames]

It doesn't matter which language is taught/learnt first, because ultimately they all contain the same format for writing programs, with minor differences in wording. Python is good to start with; C++ and Java are a bit more complex but after learning the fundamentals in Python it will make more sense. I hope C++/Java is taught later on, as well as CSS, HTML and PHP.

[@shehansithija7397]

superb.. it's very useful

[@Phaqui]

Just to clarify: At 7:26, you say that the i variable can only be used inside of the for clause. Actually the python documentation is clear on this: the i variable will not be deleted after the for clause. It can still be accessed, and will in this example point to (or contain) the number 9. docs.python.org/reference/compound_stmts.html#the-for-statement

SO how would I do 1 hello world 2 hello world 3 hello world this is my homework and when I submitted my professor said I had to do a for-loop, but nothing I'm doing is working. Please help!

[@video_games23]

for i in range(1,4): print (i,"hello world") Play around with that a little and you'll get it down. Coding can be frustrating at start.

[@MrS6]

so how would you do it without the numbers at the start of the words?

[@video_games23]

for i in range(1,4): print ("hello world")

[@1000animeboy]

for x in {1,2,3}: print x,"hello world"

[@guitaristAustin]

concatanate it. >>> print "%r hello world" %r my_var You could use a different string operator there like %i or %d (I used r just because var "i" was the default variable in the for loop)

[@profipix]

Good explanation, man! Helped me out a ton

[@adambloodworth7042]

yo this shit is helpful af

[@JackEacher]

does this mean that for loops always involve some kind of range?

[@ocean_princess]

Yes!

[@everwhat54]

this is why you need to type for i in range(5): if u forget the : it tells it the line ends here if u put : then it will read that it will keep going on and go to the next line so u can finish the program. hope you understand i am also new and learning. xD
