Code Not Working

Question

I used this code to solve the problem below in my IDE on my computer. It worked. But it won't work on Sololearn playground. I'm trying to get the sum of consecutive numbers from 1 - 50
#my code
N = int(input("Enter a number: "))
list = list(range(N))
sum = sum(list)
print (sum)

The problem below:
No one likes homework, but your math teacher has given you an assignment to find the sum of the first N numbers.

Let’s save some time by creating a program to do the calculation for you!

Take a number N as input and output the sum of all numbers from 1 to N (including N).

Sample Input
100

Sample Output
5050

Explanation: The sum of all numbers from 1 to 100 is equal to 5050.

Answer 1

Carefully read what is written in the yellow box
"Remember, range(a, b) does not include b, thus you need to use b+1 to include b in the range."
