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

Summarize for function

What am I doing wrong? Thanks guys/gals!

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(list):
  sum = 0
  for items in list: 
    sum = sum + items
  return(sum)
add_list([1, 2, 3])

def summarize(list):
  return("The sum of" + list str(list) + "is" + add_list(list) + ".")

Oops! Looks like task 1 isn't working

When Task 1 stops working, it can mean a syntax error has crept in while working on later tasks that keeps all tasks from being tested.

You're very close. You have a syntax error in your return statement. Additionally, you need to mind the spaces in the output:

def summarize(list):
    # removed extra 'list', wrapped add_list() in str(), added spaces
    return "The sum of " + str(list) + " is " + str(add_list(list)) + "."

Thanks chris freeman
