    """
    Modin distributed representation of ``pandas.DataFrame``.

    Internally, the data can be divided into partitions along both columns and rows
    in order to parallelize computations and utilize the user's hardware as much as possible.

    Inherit common for ``DataFrame``-s and ``Series`` functionality from the
    `BasePandasDataset` class.

    Parameters
    ----------
    data : DataFrame, Series, pandas.DataFrame, ndarray, Iterable or dict, optional
        Dict can contain ``Series``, arrays, constants, dataclass or list-like objects.
        If data is a dict, column order follows insertion-order.
    index : Index or array-like, optional
        Index to use for resulting frame. Will default to ``RangeIndex`` if no
        indexing information part of input data and no index provided.
    columns : Index or array-like, optional
        Column labels to use for resulting frame. Will default to
        ``RangeIndex`` if no column labels are provided.
    dtype : str, np.dtype, or pandas.ExtensionDtype, optional
        Data type to force. Only a single dtype is allowed. If None, infer.
    copy : bool, default: False
        Copy data from inputs. Only affects ``pandas.DataFrame`` / 2d ndarray input.
    query_compiler : BaseQueryCompiler, optional
        A query compiler object to create the ``DataFrame`` from.

    Notes
    -----
    ``DataFrame`` can be created either from passed `data` or `query_compiler`. If both
    parameters are provided, data source will be prioritized in the next order:

    1) Modin ``DataFrame`` or ``Series`` passed with `data` parameter.
    2) Query compiler from the `query_compiler` parameter.
    3) Various pandas/NumPy/Python data structures passed with `data` parameter.

    The last option is less desirable since import of such data structures is very
    inefficient, please use previously created Modin structures from the fist two
    options or import data using highly efficient Modin IO tools (for example
    ``pd.read_csv``).
