File "shopping_list.py", line 36, in <module>

NameError: name 'add_to_list' is not defined
" My code seems to be exact as Craig's What am I missing?

Thanks, Scott

Because of the indentation level, both "add_to_list" and "show_list" are created as internal functions of "show_help", but they should be independent so they can be accessed from the main program.

And on line 19, there is a reference to "shoppping_list" (with 3 "p"s) instead of "shopping_list".

Also, the call to "add_to_list" on line 36 has no argument, but the function is defined as needing one.

Thanks. I just watched the video again and re wrote my code, it seems exactly the same as the video but I'm still getting the same error. Any examples you could point me to? Thanks

You haven't provided a new snapshot, but here's an indent example from the previous one:

def show_help():
  print("What should I buy?")
  print("""
  ENTER 'DONE' to stop adding ites.
  ENTER 'HELP' for this help.
  ENTER 'SHOW' to see your current list.
  """)

  def add_to_list(item):  # <-- notice this line (12) is indented, but should not be
    shopping_list.append(item)
    print("Added! List has {} items.".format(len(shopping_list)))

Thanks, Steve! I just got it, it was only an indentation issue! :)
