Hey Yousef, it's kind of difficult to tell exactly what is happening without seeing the error message. From what you pasted though, it looks like you are writing the definition of each method/function on a single line. Remember to keep new statements on different lines with the proper indentation like so:

def add_to_list(item):
    shopping_list.append(item)
    print("added! list has {} items.".format(len(shopping_list)))

Let me know if restructuring your code like this helps!
