[Solved] I need to use a function in order to get a return instead printing the output

by 


def item_order(order):
    new_order = order.split()
    sal = 0
    wat = 0
    hum = 0
    for a in range(len(new_order)):
        if new_order[a] == 'salad':
            sal = sal + 1
        elif new_order[a] == 'water':
            wat = wat + 1
        elif new_order[a] == 'hamburger':
            hum = hum + 1

    return ('salad:' + str(sal) + ' ' + 'hamburger:' + str(hum) + ' ' +'water:'   + str(wat))
