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