Print a list of items in a grammatically correct way

grammatical_list.py

def grammatical_list(item_list):
    print("Entered function")
    for item in item_list:
        if item[:-1] == 's':
            item = "some " + item
        if item.startswith(('a', 'e', 'i', 'o', 'u')):
            item = "an " + item
        # print(item, sep="and, ", end='')
        print(item)
    print("Exited function")


if __name__ == '__main__':
    # should print "You see some bells, an apple, and a candle":
    grammatical_list(["bells", 'apple', 'candle'])

Try:

def grammatical_list(item_list):
    result_list = []
    for item in item_list:
        if item.endswith("s"):
            result_list.append(f"some {item}")
        elif item.startswith(('a', 'e', 'i', 'o', 'u')):
            result_list.append(f"an {item}")
        else:
            result_list.append(f"a {item}")

    # Add 'and' if we need it
    if len(result_list) > 1:
        result_list[-1] = f"and {result_list[-1]}"

    # Join it together
    return ", ".join(result_list)

👍 It worked! Thanks!
