If you want to sum the digit of a number, one way to do it is using sum() + a generator expression: I modified a little your code using sum(), maybe you want to take a look at it:
Your problem is with this line: It tries to take cow[n], which returns an integer, and make it a list. This doesn’t work, as demonstrated below: Perhaps you meant to put cow[n] inside a list: See a demonstration below: Also, I wanted to address two things: Your while-statement is missing a : at the end. It is considered very dangerous to … Read more
