Could someone help with the Functions code challenge?

I am completely baffled by this code challenge. I don't know where to start. I barely understand how the for loops work, and I have forgotten how to add the values together. Could anyone give me advice on how to complete this code challenge?

Here's my answer:

def add_list(x):
  total = 0
  for item in x:
    total = total + item

  return total

def summarize(my_list):
  y = add_list(my_list)
  return "The sum of {} is {}".format(str(my_list), y)

Here's the answer, please ask if you didn't understand something:

# add_list([1, 2, 3]) should return 6
# summarize([1, 2, 3]) should return "The sum of [1, 2, 3] is 6."
# Note: both functions will only take *one* argument each.

def add_list(my_list):
    total_sum = 0
    size = len(my_list)
    for number in range(size):
        total_sum += my_list[number]

    return total_sum


def summarize(other_list):
    total_sum = add_list(other_list)   #here we may use the function defined before
    my_string = "The sum of {} is {}".format(other_list,total_sum)

    return my_string
