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

In the python basics functions quiz, i'm getting a positional argument error, yet my code works on my computer.

What am I doing wrong?

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.


list = [1,2,3]

def add_list():
  output = sum(list)
  print("the sum of {} is {}".format(list,output))

add_list()

Hi,

You have the right idea, but the add_list function is suppose to take in the list as an argument. The list [1,2,3] is just an example.

Also it asks that the function simply to return the result. No need to print anything.

This worked for me

def add_list(a_list):
  output = sum(a_list)
  return output

This ^ The biggest thing to note is that every you are trying to use a value from a function, you want to use the return command.
