pythonfor-loopcycle

Python.The problem is in solving the problem with cycles

The sum() function takes a series of numbers (a string) and returns their sum.

def sum(numbers):
    result = 0
    for num in:
        result += 
    return result

sum("12345")  # 15

I started learning the language recently. In one of the sites I came across this problem that I can not solve.

def sum(numbers):
    result = 0
    for num in numbers:
        result += 1

This is how I see the solution to this problem, but it is not correct.

Solution

  • You have to convert str num to int before adding:

    def sum1(numbers):
    result = 0
    for num in numbers:
        result += int(num)  # add each number from numbers
    return result

sum1('12345')

#15
