python - Print the sum of a list of integers without using sum()

Question

I have a function defined below that prints each integer in the list, and it works perfectly. What I would like to do is create a second function that would call on or reutilize the int_list() function to display a sum of the list that's been generated.

I am not sure if that has been inherently performed by the code itself - I am rather new to the Python syntax.

integer_list = [5, 10, 15, 20, 25, 30, 35, 40, 45]

def int_list(self):
    for n in integer_list
        index = 0
        index += n
        print index

Answer 1

In your code, you're setting index=0 in every loop, so it should be initialized before the for loop:

def int_list(grades):   #list is passed to the function
    summ = 0 
    for n in grades:
        summ += n
        print summ

output:

int_list([5, 10, 15, 20, 25, 30, 35, 40, 45])
5
15
30
50
75
105
140
180
225
