Confused about not using input()

The task is asking: Make a function named add_list that takes a list. The function should then add all of the items in the list together and return the total. Assume the list contains only numbers. You'll probably want to use a for loop. You will not need to use input().

What may not be clear is you do not have to provide an input or function calling mechanism in your code. When you click on the "Check Work" button, a grader will be invoked which both calls your code with test data and also checks the returned values.

For this task you need to return the sum of the items in the input list. Adding hints to your code:

#add_list = [] #<-- global not needed
def add_list(number_list): #<-- change name to "add_list". Name must match task so grader can properly call it;
                          # Renamed parameter to indicate list
  add_list.append(number_list) # <-- REPLACE this statement with code that adds up the items in number_list
  return total #<-- add return statement so the calling code can see the result placed in a variable (called total in this case)
# Not needed:
#def show_list():
#  print("the sum of")
#  for number in add_list:
#    print(number)
#    print("is 6")
#show_list()
