Error: string_factory() missing 1 required positional argument: 'template', but works in IDE

Heres my code, I keep getting the error mentioned in the title:

dicts = [ {'name': 'Michelangelo', 'food': 'PIZZA'}, {'name': 'Garfield', 'food': 'lasanga'}, {'name': 'Walter', 'food': 'pancakes'}, {'name': 'Galactus', 'food': 'worlds'} ]

template = "Hi, I'm {name} and I love to eat {food}!"

def string_factory(dicts, template): strings = [] for items in dicts: strings.append(template.format(**items)) return strings

string_factory(dicts, template)

template is a global variable established outside of the loop, I don't think you have to pass it to the routine, however I'm not sure that is what the issue is

You should only take one argument.

The instructions say to write a function "that accepts a list of dictionaries as an argument". But your function requires a list of dictionaries and a template. You'll make use of the global template in your function, you won't get one as an argument.

And just define your function. Don't also call it (or define your own list of dicts).
