from faker import Faker

fake = Faker()
fake.add_provider(faker_commerce.Provider)


QUANTITY = 100


with open('/tmp/products.csv', 'w', newline='') as csvfile:
    writer = csv.writer(csvfile)
    writer.writerow(['title', 'price'])
    for _ in range(QUANTITY):
        short_uuid = uuid.uuid4().hex[:8]
        title = f'{fake.ecommerce_name()} {short_uuid}'
        price = round(random.uniform(1, 100), 2)
        writer.writerow([title, price])
