Python - How to sum a certain section of a list

I have a list of 90 values and I would like to find the value of the sum of the first 30 of these values. Is there a way I can do this easily?

Simplest way to do is slice the list and use sum function

ans = sum(input[:30])

If you want to add numbers between a particular range let's say you want to add numbers between 20-30(inclusive) then you can do that as

ans = sum(input[20:31])

The easiest would be to just slice it:

result = sum(lst[0:30])

You can use the following command:

l = [1,2,3,4,5.....90]
s = sum(l[:30])
