I tried, but I can't success. So please I need help?.
# 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(numbers):
for number in numbers:
return total
def summarize(add_list):
return "The sum of {} is .".format(add_list)

def add_list(numbers):
# Be mindful of the indentation, it's how Python
# recognizes blocks of code.
# Declare the total variable, intializing to 0
total = 0
for number in numbers:
# Equivalent to total = total + number
total += number
# Return outside the for block, otherwise only
# one iteration will happen.
return total
The summarize function needs to format the list and the total:
def summarize(numbers):
return "The sum of {numbers} is {total}".format(numbers=numbers, total=add_list(numbers))
format knows how to deal with lists, so you don't have to do anything extra when passing it in.

1,329 PointsThanks Dan. I set up like this ,but still I can't pass. Because indent errors for return. I did tap one time and two times still won't go through. Any suggestions?.
add_list =(1, 2, 3)
def add_list(numbers):
total = 0
for number in numbers:
total += number
return total
def summarize(numbers):
return "The sum of {numbers} is {total}".format(numbers=numbers, total=add_list(numbers))

1,329 PointsDan sorry return is under the total. Not what you see.

40,533 PointsIf you have total in line with the rest of the function block, then all you need to do to get it to work is move the for loop back in:
def add_list(numbers):
total = 0
for number in numbers:
total += number
return total
Also don't worry about defining your own list. The challenge will take care of that for you.
