Tutorial on nested loops

[@Viswesh]

First example is made very complex. This code will be simple. n=int(input("Enter number: ")) for i in range(2,n): flag=True for j in range(2,i): if i%j==0: flag=False break if flag: print(i) It could be made even simpler by using else block to the inner for loop, thereby eliminating the need for a Flag variable.

Thank you.

[@alexioscarlos7727]

I think this code is wrong bcoz n==2 then it would make flag false which is not true

[@MUTHU_KRISHNAN_K]

​@@alexioscarlos7727for n==2 , nothing should be printed, right?since there is no prime number lesser than 2.

I think you forgot to mention the end=' ' in the program according to above same output

[@smokyvibes]

much better if you check until root(i) since after thats its just gonna be multiple of them.

I understand this is tutorial still they should show him type while explaining what's the logic, instead of directly taking us to the screen with already typed code

[@aryangarg7359]

thats the whole dissapointment actually, there are many a times they have missed explaining important things like flag where to use when to use , just teaching like a novel story.

Coming soon to iit

[@Adityakumar-pn7yq]

this my code sample example num= int(input()) prime= 0 for i in range(2, num): for j in range(1, i): if j!= 1 and i%j == 0: break if j== i-1: print(i, end= " ")

20:17 in test case 5 , we don't have input -1 in the statement but in the code You have given.

[@RohitRajSharma-kh6iu]

I think that is a printing mistake in the statements

[@ManishKumar-qr4hb]

I don't know why.... but i feel this lecture little harder

[@selvamselvam7960]

What is the use of flag function true false anyone let me explain plz

I believe,by now,you would have no doubt on this topic.but,it may help someone else:😊 Reason for flag It's actually a more professional way, maybe,I don't know.its job is to hold 'false' if the number is not prime and to possess 'true' if the number is prime. It's usage can be completely eliminated,by using 'print' statement directly under 'else' condition 🙂👍

थैंक्यू

[@sayanghosh6996]

for these conditions a do-while statement is better suited. shame that python doesnt have it though 😔

[@MUTHU_KRISHNAN_K]

Is it sir?😮 I am on the initial weeks and not aware of this. Btw,you may know me from Linux course Jan 2024 term.electronic systems😀

#find all prime numbers less than entered number num = int(input('Enter the number: ')) if(num>2): print(2,end=" ") for i in range(3, num): if i % 2 != 0: print(i, end = " ", sep = "-")

[@nikulpd8137]

its wrong
