>>> tg = csvw.TableGroup.from_file('tests/csv.txt-metadata.json')
>>> tg.check_referential_integrity()
>>> assert len(tg.tables) == 1
>>> assert tg.tables[0] is tg.tabledict['csv.txt']
>>> tg.tables[0].check_primary_key()
>>> from collections import OrderedDict
>>> row = next(tg.tables[0].iterdicts())
>>> assert row == OrderedDict([('ID', 'first'), ('_col.2', 'line')])
>>> assert len(list(tg.tables[0].iterdicts())) == 2
Known limitations
- We read all data which is specified as UTF-8 encoded using the
utf-8-sig
codecs. Thus, if such data starts withU+FEFF
this will be interpreted as BOM and skipped. - Low level CSV parsing is delegated to the
csv
module in Python's standard library. Thus, if acommentPrefix
is specified in aDialect
instance, this will lead to skipping rows where the first value starts withcommentPrefix
, even if the value was quoted.
