Define the function first using the def keyword, and it takes a list as an argument. You can just put a variable name, like blah as the argument. add_list(blah). create a variable to hold onto the sum that you can return at the end, you can just set it to 0 for now. then run a for loop to add the parts of the list together, for x in blah. during the for loop, add the part of the list you are cycling through to the variable you created. sum = sum + x. And finally return the sum. At least, that is how I did it.
