I'm trying to create a simple program that tells you your lucky number according to numerology. I keep on getting this error:

```
File "number.py", line 12, in <module>
sumln = (int(sumall[0])+int(sumall[1]))
TypeError: 'int' object is not subscriptable
```

My script is:

```
birthday = raw_input("When is your birthday(mm/dd/yyyy)? ")
summ = (int(birthday[0])+int(birthday[1]))
sumd = (int(birthday[3])+int(birthday[4]))
sumy= (int(birthday[6])+int(birthday[7])+int(birthday[8])+int(birthday[9]))
sumall = summ + sumd + sumy
print "The sum of your numbers is", sumall
sumln = (int(sumall[0])+int(sumall[1]))
print "Your lucky number is", sumln`
```

If you want to sum the digit of a number, one way to do it is using `sum()`

+ a generator expression:

```
sum(int(i) for i in str(155))
```

I modified a little your code using `sum()`

, maybe you want to take a look at it:

```
birthday = raw_input("When is your birthday(mm/dd/yyyy)? ")
summ = sum(int(i) for i in birthday[0:2])
sumd = sum(int(i) for i in birthday[3:5])
sumy = sum(int(i) for i in birthday[6:10])
sumall = summ + sumd + sumy
print "The sum of your numbers is", sumall
sumln = sum(int(c) for c in str(sumall)))
print "Your lucky number is", sumln
```

The error is exactly what it says it is; you're trying to take `sumall[0]`

when `sumall`

is an int and that doesn't make any sense. What do you believe `sumall`

should be?
