 def expect_column_to_exist( self, column, column_index=None, result_format=None, include_config=False, catch_exceptions=None, meta=None ):
 """Expect the specified column to exist. expect_column_to_exist is a :func:`expectation <great_expectations.data_asset.dataset.Dataset.expectation>`, not a \ `column_map_expectation` or `column_aggregate_expectation`. Args: column (str):
 \ The column name. Other Parameters: column_index (int or None):
 \ If not None, checks the order of the columns. The expectation will fail if the \ column is not in location column_index (zero-indexed). result_format (str or None):
 \ Which output mode to use: `BOOLEAN_ONLY`, `BASIC`, `COMPLETE`, or `SUMMARY`. For more detail, see :ref:`result_format <result_format>`. include_config (boolean):
 \ If True, then include the expectation config as part of the result object. \ For more detail, see :ref:`include_config`. catch_exceptions (boolean or None):
 \ If True, then catch exceptions and include them as part of the result object. \ For more detail, see :ref:`catch_exceptions`. meta (dict or None):
 \ A JSON-serializable dictionary (nesting allowed) that will be included in the output without modification. \ For more detail, see :ref:`meta`. Returns: A JSON-serializable expectation result object. Exact fields vary depending on the values passed to :ref:`result_format <result_format>` and :ref:`include_config`, :ref:`catch_exceptions`, and :ref:`meta`. """
