Great video. But This code is saying 9,15,21... are prime numbers but they are not. Any idea why?

[@madiripadma3877]

Prime number means the number divisible by 1 and itself.for eg : 5 5 is divisible by 1 and 5 only so it is prime number.

[@AdityaThakur-cq1ov]

I think something wrong with this code.... it's say 49 is prime .....kese......

[@karthikchinna3621]

it will say 13 is not prime wrong

[@asishkumarpatro5903]

Bhai infinite prime h tu aise nahi kar sakta

[@manjari400]

This code is not working appropriately for 2 and the odd numbers that are non prime number like 15,21,9 etc.

[@AshishVerma13yq]

Same doubt

[@Staredits006]

Same

[@badalmishra7395]

It is working fine. I think the problem you got is with "else" . You need to shift it as she said backwards

[@asishkumarpatro5903]

​@@badalmishra7395but shouldn't if and else statements be in the same indentation?

[@badalmishra7395]

@@asishkumarpatro5903 yes correct. But in this case if you use the same indentation as "if" in the for loop, it will throw "it is a prime number " multiple time , to break that loop for the output printed once, we need to get that else out of that for loop indentation or use the same indentation used for "for loop" statement. Secondly else should be the same indentation as "if" -True , but , here we have 3 ifs', and the code determines what should be the indentation of else. That's how loop function works

[@abhijeetsinghyadav8988]

n= int(input("Enter any number: ")) if (n%n==0) and (n%2!=0) and (n>1): print("Given number is a prime ") else: print("No is not a prime ")

[@akashrai5253]

This same condition is apply to many numbers like 15 when it is divided by 2 it will not return 0 but it is not a prime number, so this condition will not work even mam's condition is also not working.

[@oxivrushab2573]

Can we use only in if condition using or like number which divides by 2,3,4,5,7,6,8,9,11 are not prime else are prime my work effectively

[@itzmasum1079]

With this code please try input "2"

[@Aditya_Deshmukh]

Is there a need for a for loop in this example

How about 2?

[@raosajid6578]

9 is does not satisfy your code if user enter 9 then it will give us it is prime but it is not

[@rohitraj7914]

9 jb enter krenge to num=9 ho jayega to loop 2-8 tk hi chlega. So condition is satisfying for 9 also.
