Construct a Frame from an iterable of rows, where rows are defined as iterables, including tuples, lists, and arrays. If each row is a NamedTuple, and columns is not provided, column names will be derived from the NamedTuple fields.

Supplying dtypes will significantly improve performance, as otherwise columnar array types must be derived by element-wise examination.

For records defined as Series, use Frame.from_concat; for records defined as dictionary, use Frame.from_dict_records; for creating a Frame from a single dictionary, where keys are column labels and values are columns, use Frame.from_dict.

Parameters

records – Iterable of row values, where row values are arrays, tuples, lists, or namedtuples. For dictionary records, use Frame.from_dict_records.
index – Optionally provide an iterable of index labels, equal in length to the number of records. If a generator, this value will not be evaluated until after records are loaded.
columns – Optionally provide an iterable of column labels, equal in length to the number of elements in a row.
dtypes – Optionally provide an iterable of dtypes, equal in length to the length of each row, or a mapping by column name. If a dtype is given as None, NumPy’s default type determination will be used.
name – A hashable object to label the container.
consolidate_blocks – Optionally consolidate adjacent same-typed columns into contiguous arrays.

Returns

Frame

Return a new Frame after removing rows (axis 0) or columns (axis 1) where any or all values are NA (NaN or None). The condition is determined by a NumPy ufunc that process the Boolean array returned by isna(); the default is np.all.

Parameters

FrameGO.duplicated(*, axis: int = 0, exclude_first: bool = False, exclude_last: bool = False) → static_frame.core.series.Series

Return an axis-sized Boolean Series that shows True for all rows (axis 0) or columns (axis 1) duplicated.

Parameters

axis – Integer specifying axis, where 0 is rows and 1 is columns. Axis 0 is set by default.
exclude_first – Boolean to select if the first duplicated value is excluded.

FrameGO.equals(other: Any, *, compare_name: bool = False, compare_dtype: bool = False, compare_class: bool = False, skipna: bool = True) → bool

Return a bool from comparison to any other object.

Parameters

compare_name – Include equality of the container’s name (and all composed containers) in the comparison.

FrameGO.extend(container: Union[static_frame.core.frame.Frame, static_frame.core.series.Series], fill_value: Any = nan) → None[source]

Extend this FrameGO (in-place) with another Frame’s blocks or Series array; as blocks are immutable, this is a no-copy operation when indices align. If indices do not align, the passed-in Frame or Series will be reindexed (as happens when adding a column to a FrameGO).

If a Series is passed in, the column name will be taken from the Series name attribute.

This method differs from FrameGO.extend_items() by permitting contiguous underlying blocks to be extended from another Frame into this Frame.

FrameGO.extend_items(pairs: Iterable[Tuple[Hashable, static_frame.core.series.Series]], fill_value: Any = nan) → None[source]: Given an iterable of pairs of column name, column value, extend this FrameGO. Columns values can be any iterable suitable for usage in __setitem__.
