How to sum the digits of integers in a list?

Question

I'm trying to get a sum of digits list from an integer list.

In:

 list=[12,37,44,96]

Out:

[3,10,8,15]

I have tried tons of methods and havent solved yet.

^^If you have a function that'll work on a single number, you can use list comprehension or `map()` to apply to all list numbers — OneCricketeer, Oct 28 '18 at 21:44

This one-liner should do:

result = [sum(int(digit) for digit in str(number)) for number in lst]

Basically you have to go from int to strings to get the digits and then back to ints to be able to sum them up.

Note: I renamed your list variable to lst to avoid confusion between variable names and keywords.
