How I can solve it by using range. Help . I DON'T KNOW HOW TO START.

Question

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

Use the Gauss formula like Jan Markus suggested. It is much faster.

Answer 2

Id start with
for x in range(N + 1):
And for each iteration add x to a variable
