How to retrieve the Fact weight?

[jfraschilla]

Hi Dwight,

Issue #334 talks about how the numeric values get a weight applied to them.
How do you retrieve the weight value?
When I retrieve a Fact using execute(), I do not see a 'weight' field. Example for COST most recent 10-K:

Example query:

xbrl_data.query().by_period_key(period_key).by_concept('us-gaap:CostOfGoodsAndServicesSold').execute()

Output:

[{'fact_key': 'us-gaap_CostOfGoodsAndServicesSold_c-1',
  'concept': 'us-gaap:CostOfGoodsAndServicesSold',
  'context_ref': 'c-1',
  'value': '-222358000000',
  'unit_ref': 'usd',
  'decimals': '-6',
  'numeric_value': -222358000000.0,
  'period_type': 'duration',
  'period_start': '2023-09-04',
  'period_end': '2024-09-01',
  'entity_identifier': '0000909832',
  'entity_scheme': 'http://www.sec.gov/CIK',
  'period_key': 'duration_2023-09-04_2024-09-01',
  'label': 'Cost of Goods and Services Sold',
  'original_label': 'Cost of Goods and Services Sold',
  'statement_type': 'IncomeStatement',
  'statement_role': 'http://www.costco.com/role/ConsolidatedStatementsOfIncome'}]

Also, in issue #334 you mention "I turned off the negation and ran for a list of popular companies". How can a user of the library turn off negation?

Thanks
