Series Summation using for loop in python

Question

Let's say that we are having some series as below:

1+2+3+....+n

In c with for loop, we can easily do this:

for(i=1;i<=n;i++)

{

    sum += i;

}

In Python, I am able to do this using while loop:

while(num <= n):

      sum += num

      num = num+1

But not with for loop.

Answer 1

I guess its similar to C only

for i in range(n):

     sum+=i
