Python Python Basics (Retired) Putting the "Fun" Back in "Function" Functions

converting a list to a string

i can't convert a list to a string in a function

functions.py
# 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(list1):
  sum_of_list = 0
  for number in list1:
    sum_of_list += number
  return sum_of_list

def summarize(list1):

    sum_of_list = 0
    summary = 0
    for number in list1:
        sum_of_list += number

    x_string = list1
    summary = 'The sum of'+str(x_string)+'is'+sum_of_list
    return summary

Hi! I think u need convert "sum_of_list" to string type. Like this:

def summarize(list1):

    sum_of_list = 0
    summary = 0
    for number in list1:
        sum_of_list += number

    x_string = list1
    #sum_of_list is number type, need use str() function for string operation
    summary = 'The sum of'+str(x_string)+' is '+str(sum_of_list)
    return summary
