help with python 33 code project

Question

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

Given code is
N = int(input())

I don’t know where to go from there? Please help. I need to turn N into a list first, but I’m not sure how to do that

Answer 1

Use range() and a for-loop.

Answer 2

Here are a few solutions:
N = int(input())

# You could iterate over the range of 0...N and aggregate the sum.
sum = 0
for i in range(N + 1): # loop i over 0...N inclusive
sum += i

print(sum)

# You could optimize down to the following expression:
print(int((N + 1) * N / 2))

Answer 3

N = int(input())
sum = 0
for i in range(N+1):
sum += i
print(sum)
print(int(N + 1)*N / 2))
