For instance if I have the string entered 345. I want them to be added 3 + 4 + 5. I've seen this here before just can't seem to find it again. Thanks!

Maybe it's my Scheme getting to me, but I'd use map here. map(int, s) says "take this sequence but with all its elements as integers". That is, it's the same as [int(x) for x in s], but faster to read/type.
>>> x = "345"
>>> sum(map(int, x))
12

map is more pythonic than a generator expression in this case.

What is map for? and what does it do?
s = raw_input()
print sum(int(c) for c in s.strip())

In [4]: text='345'
In [5]: sum(int(char) for char in text)
Out[5]: 12
or if you want the string 3+4+5:
In [8]: '+'.join(char for char in text)
Out[8]: '3+4+5'

What Python shell do you use?
What unutbu said plus, if the number is an int, not a string:
num = 345
sum([int(x) for x in str(num)])
