apply apriori on it by using data generator but how can I print results

Question

Here is my code for my large dataset with more than 400000 rows and 18 columns.

def data_generator(df):
  """
  Data generator, needs to return a generator to be called several times.
  Use this approach if data is too large to fit in memory.
  """
  def data_gen():
        yield [tuple(row) for row in df.values.tolist()]

  return data_gen
records=data_generator(df)
iterator = iter(association_rules)
while True:
  try:
    rule = next(iterator)
    print(rule)
  except StopIteration:
    break

Traceback:
