(Solved) Why my code doesn't work????🤔

Question

N=int(input())
sum=0
for i in range(N+1):
sum+=i
print(sum)

Answer 1

Ayda Tazh ,

It does work (assuming you input a non-negative integer). I inputted 5, and it printed 15, which is the sum of 0 + 0 + 1 + 2 + 3 + 4 + 5.

But you could make it look better. Variable names should be lowercase. Operators should be surrounded by single spaces. Indentation should be four spaces per level.

n = int(input())
sum = 0
for i in range(n + 1):
sum += i
print(sum)

Answer 2

Can you share the input and expected output then we can modify your code accordingly

Answer 3

Ok

Answer 4

It does work with N same as n

N=int(input())
sum=0
for i in range(N+1):
sum+=i
print(sum)

Answer 5

Ok 👌🏽

Answer 6

I sloved it, thanks

Yes, N is a legal name, so the code runs, but the naming convention is that variable names should use snake_case,

https://peps.python.org/pep-0008/#function-and-variable-names

and class names should use CapitalizedWords.

There are more naming conventions too. Here's a good third-party table that summarizes them (rotate the phone to landscape aspect).

Answer 8

Try adding the if loop to n must be greater than or equal to 0
n=int(input ())
s=0
if n>=0:
{
for i in range(n+1) :
s+=i
print(sum)
}

If it's solved, will you add [Solved] to the title so people reading the list of titles know they don't need to help?
