Description:
 def with_columns(self, *labels_and_values):
 """Return a table with additional or replaced columns. Args: ``labels_and_values``: An alternating list of labels and values or a list of label-value pairs. If one of the labels is in existing table, then every value in the corresponding column is set to that value. If label has only a single value (``int``), every row of corresponding column takes on that value. Raises: ``ValueError``: If - any label in ``labels_and_values`` is not a valid column name, i.e if label is not of type (str). - if any value in ``labels_and_values`` is a list/array and does not have the same length as the number of rows in the table. ``AssertionError``: - 'incorrect columns format', if passed more than one sequence (iterables) for ``labels_and_values``. - 'even length sequence required' if missing a pair in label-value pairs. Returns: Copy of original table with new or replaced columns. Columns added in order of labels. Equivalent to ``with_column(label, value)`` when passed only one label-value pair. player_id | wOBA 110,234 | 0.354 110,235 | 0.236 player_id | wOBA | salaries | season 110,234 | 0.354 | N/A | 2,016 110,235 | 0.236 | N/A | 2,016 player_id | wOBA | salaries | season | years 110,234 | 0.354 | $500,000 | 2,016 | 6 110,235 | 0.236 | $15,500,000 | 2,016 | 1 Traceback (most recent call last):
