Hey mate. This is my first attempt at helping anyone. Mostly there were simple errors that such as spelling errors, incorrect spacings (make sure you set your workspace to 4 spaces), and forgetting brackets in places. I added comments where I changed stuff. Hopefully it helps.

 shopping_list = []


def show_help():
    print("\nSeperate each item with a comma.")
    print("Type DONE to quit, SHOW to see the current list, HELP to get the help message.")


def show_list():
    count = 1 
    for item in shopping_list:
        print("{}: {}.".format(count, item))  # This had a double bracket after .format((
        count += 1

print("Give me a list of things you want to shop for.")
show_help()


while True:
    # CORRECTIONS - Make sure that spacing is correct. 4 spaces - most were only 2 spaces or 1 etc
    new_stuff = input(">")

    if new_stuff == "DONE":
        print("\nHere's your list!")
        show_list()
        break
    elif new_stuff == "HELP":
        show_help()
        continue
    elif new_stuff == "SHOW":
        show_list()  # Wrote as show_list not show_list()
        continue
    else:
        new_list = new_stuff.split(",")
        index = input("Add this at aH certain spot? Press enter for the end of the list, "
                "or give me a number. Currently {} items in the list.".format(len(shopping_list)))
    if index:
        spot = int(index) - 1
        for item in new_list:
            # Need to make sure this was inside the loop
            shopping_list.insert(spot, item.strip())  # had : instead of a closing brackets
            spot += 1
    else:
        for item in new_list:
            # Needed to make sure this was inside the loop to
            shopping_list.append(item.strip())  #spelling error --> changed sjhopping_list to shopping_list

[MOD: added 'python' to the markdown block code for colorization. -- cf]
