Iterating over a list in a function


#1

numbers = [3, 5, 7]

def total(numbers):
result = 0
for i in range(0, len(numbers)):
result = result + i
return result

print total()

This give me an error of : Oops, try again. total([0, 3, 6]) returned 3 instead of 9
.

i in this instance will be an integer, acting as an index.

result be no more than the sum of the indexes, not the sum of the items.

To sum up the values at each index,

result += numbers[i]

It is possible to write the assignment the way you have it, but the loop will need to be a value loop (look up) rather than index loop.

for i in numbers:
    result += i

assuming of course that i is a number.
