I'm not able to add given list

Question

**Not able to add the given list a

a = ['1','2','3','4','5','6']


    def sums (a):
        return sum(a)

    print(sums(a))

gives me error unsupported operand type(s) for +: 'int' and 'str'

i understand that i can’t add list of str implicitly without converting them to int, but when i try to convert the list a into int

a = ['1','2','3','4','5','6']


def sums (a):
    int_a = int(a)
    return sum(a)

print(sums(a))

it still gives me the error **

int() argument must be a string, a bytes-like object or a number, not 'list'

just a learner,
any help would be much appreciated!

Answer 1

When you do

int_a = int(a)

The code tries to convert the list a to an int. What you need to do is

def sums (a):
    a = [int(x) for x in a]
    return sum(a)

This converts each element in the list to an integer. You could cut this down even further to

def sums (a):
    return sum(int(x) for x in a)
