Python, a sum() issue

I have been trying to compute the total sum of all these ords so I have decided to use the sum() built in function.

What happens though it outputs the sum total x4 when I run the script. Anyone know why?

T = ord('a'), ord('b'), ord('c'), ord('d')

for c in T:
    c = sum(T)
    print(c)

edit:

T = "hi chris"

total = 0
for c in T:
    total += ord(c)
    print(total)

This seems to be working but its calculation each one individually, i want 1 sum and the total, not each characters total individually...

Your for loop is incorrect. You are re-calculating the sum of T with each loop. Instead of doing this:

for c in T:
    c = sum(T)
    print(c)

do this:

print(sum(T))

or this:

s = 0
for c in T:
    s += c
print(s)

You don't need to put the sum in a loop. It automatically works on the whole list.

total = sum(T)

Alternatively, don't use sum:

total = 0
for c in T:
    total += c

in which case you can use a loop.

For a bit more info, see the built-in functions docs.
