adding numbers in a string in python

Question

I have a string of numbers, for example 12458960. How can I go about adding them so that it would be 1+2+4+5+8+9+6+0 = 35

I have the numbers already recorded into a variable called ccn. I just need to get the sum now. I tried adding the string numbers using,

ccn[0]+ccn[1]+ccn[2]+ccn[3]+ccn[4]+ccn[5]+ccn[6]+ccn[7]

But that didnt work.

Any help would be much appreciated.

Please update your question with the code you have tried. You must have more code than: `ccn[0]+ccn[1]+ ...` — quamrana, May 26 '20 at 14:05
Also add what is wrong or what error you are getting. I have a feeling that error could lead you to the solution... — Tomerikoo, May 26 '20 at 14:06
If all the elements of string are numbers then try this `sum(map(int,num))` else look at @Tomerikoo 's comment. — Ch3steR, May 26 '20 at 14:07

You can do this:-

a = '12458960'
res = sum(map(int, a))
print(res)

Output:-

Try with this one liner:

a = '12458960'
print (sum(int(i) for i in a))

Probably as well to use Python 3 style print syntax now that Python 2 is obsolete – David Buck May 26 '20 at 14:11

Here is a very basic way:

num = '123458960'
number = 0
for n in num:
    number += int(n)
print(number)
