Line by line input sum

Beginner question

I have an input like this:

5 8 9 2 1    # = 25
1 2 0 1 9    # = 13
5 7 9 10 2   # = 33

That is separated per lines and between values/individual inputs we have an space.

I need to write code that stores the sum of these values line by line and store them into a variable, like a1 = the sum of input line 1, a2 = the sum of input line 2.

a1 will be 25, a2 will be 13, and a3 will b 33.

Which function i use to write this the way that I want?

Extra question: How to store them individually in a list or a variable? Like, a1 = the inputs in the line1, a2 = inputs in the line2, without adding them, I can only do this with lists?

>Solution :

You can do this:

def main():
    a = input()
    l = list()
    total = 0
    while a != 'e':
        for token in a.split():
            try:
                total += int(token)
            except ValueError:
                return -1
        l.append(total)
        total = 0
        a = input()
    print(l)
    return 0


if __name__ == "__main__":
    main()

… type ‘e’ as input to quit.

If you enter a non-numeric character (like a letter) the function automatically quits and the program ends.
