class DataFrame:
    """A distributed collection of data grouped into named columns.

    .. versionadded:: 1.3.0

    .. versionchanged:: 3.4.0
        Supports Spark Connect.

    Examples
    --------
    A :class:`DataFrame` is equivalent to a relational table in Spark SQL,
    and can be created using various functions in :class:`SparkSession`:

    >>> people = spark.createDataFrame([
    ...     {"deptId": 1, "age": 40, "name": "Hyukjin Kwon", "gender": "M", "salary": 50},
    ...     {"deptId": 1, "age": 50, "name": "Takuya Ueshin", "gender": "M", "salary": 100},
    ...     {"deptId": 2, "age": 60, "name": "Xinrong Meng", "gender": "F", "salary": 150},
    ...     {"deptId": 3, "age": 20, "name": "Haejoon Lee", "gender": "M", "salary": 200}
    ... ])

    Once created, it can be manipulated using the various domain-specific-language
    (DSL) functions defined in: :class:`DataFrame`, :class:`Column`.

    To select a column from the :class:`DataFrame`, use the apply method:

    >>> age_col = people.age

    A more concrete example:

    >>> # To create DataFrame using SparkSession
    ... department = spark.createDataFrame([
    ...     {"id": 1, "name": "PySpark"},
    ...     {"id": 2, "name": "ML"},
    ...     {"id": 3, "name": "Spark SQL"}
    ... ])

    >>> people.filter(people.age > 30).join(
    ...     department, people.deptId == department.id).groupBy(
    ...     department.name, "gender").agg(
    ...         {"salary": "avg", "age": "max"}).sort("max(age)").show()
    +-------+------+-----------+--------+
    |   name|gender|avg(salary)|max(age)|
    +-------+------+-----------+--------+
    |PySpark|     M|       75.0|      50|
    |     ML|     F|      150.0|      60|

        >>> df = spark.createDataFrame([(1, (2, 2))], ["a", "b"])
        >>> df.printSchema(1)
        root
         |-- a: long (nullable = true)
         |-- b: struct (nullable = true)

        Example 3: Printing the schema with deeper nesting level

        However, if you're doing a drastic coalesce, e.g. to numPartitions = 1,

        you like (e.g. one node in the case of numPartitions = 1). To avoid this,

        Parameters
        ----------
        numPartitions : int
            can be an int to specify the target number of partitions or a Column.
            If it is a Column, it will be used as the first partitioning column. If not specified,
            the default number of partitions is used.
        cols : str or :class:`Column`
            partitioning columns.

        Returns
        -------
        :class:`DataFrame`
            Repartitioned DataFrame.

        Notes
        -----
        At least one partition-by expression must be specified.
        When no explicit sort order is specified, "ascending nulls first" is assumed.

        Due to performance reasons this method uses sampling to estimate the ranges.
        Hence, the output may not be consistent, since sampling can return different values.
        The sample size can be controlled by the config
        `spark.sql.execution.rangeExchange.sampleSizePerPartition`.

        Examples
        --------
        Repartition the data into 2 partitions by range in 'age' column.
        For example, the first partition can have ``(14, "Tom")`` and ``(16, "Bob")``,
        and the second partition would have ``(23, "Alice")``.

        >>> from pyspark.sql import functions as sf

        Returns a new :class:`DataFrame` partitioned by the given partition ID expression.
        Each row's target partition is determined directly by the value of the partition ID column.

        .. versionadded:: 4.1.0

        .. versionchanged:: 4.1.0
            Supports Spark Connect.

        Parameters
        ----------
        numPartitions : int
            target number of partitions
        partitionIdCol : str or :class:`Column`
            column expression that evaluates to the target partition ID for each row.
            Must be an integer type. Values are taken modulo numPartitions to determine
            the final partition. Null values are sent to partition 0.

        Returns
        -------
        :class:`DataFrame`
            Repartitioned DataFrame.

        Notes
        -----
        The partition ID expression must evaluate to an integer type.
        Partition IDs are taken modulo numPartitions, so values outside the range [0, numPartitions)
        are automatically mapped to valid partition IDs. If the partition ID expression evaluates to
        a NULL value, the row is sent to partition 0.

        This method provides direct control over partition placement, similar to RDD's
        partitionBy with custom partitioners, but at the DataFrame level.

        Examples
        --------
        Partition rows based on a computed partition ID:

        | Bob|  5|  NULL|
        +----+---+------+

        Outer join on a single column with an explicit join condition.

        When the join condition is explicited stated: `df.name == df2.name`, this will
        produce all records where the names match, as well as those that don't (since
        it's an outer join). If there are names in `df2` that are not present in `df`,
        they will appear with `NULL` in the `name` column of `df`, and vice versa for `df2`.

        >>> joined = df.join(df2, df.name == df2.name, "outer").sort(sf.desc(df.name))
        >>> joined.show()
        +-----+----+----+------+
        | name| age|name|height|
        +-----+----+----+------+
        |  Bob|   5| Bob|    85|
        |Alice|   2|NULL|  NULL|
        | NULL|NULL| Tom|    80|
        +-----+----+----+------+

        To unambiguously select output columns, specify the dataframe along with the column name:

        >>> joined.select(df.name, df2.height).show()
        +-----+------+
        | name|height|
        +-----+------+
        |  Bob|    85|
        |Alice|  NULL|
        | NULL|    80|
        +-----+------+

        However, in self-joins, direct column references can cause ambiguity:

        >>> df.join(df, df.name == df.name, "outer").select(df.name).show() # doctest: +SKIP
        Traceback (most recent call last):
        ...
        pyspark.errors.exceptions.captured.AnalysisException: Column name#0 are ambiguous...

        A better approach is to assign aliases to the dataframes, and then reference
        the output columns from the join operation using these aliases:

        >>> df.alias("a").join(
        ...     df.alias("b"), sf.col("a.name") == sf.col("b.name"), "outer"
        ... ).sort(sf.desc("a.name")).select("a.name", "b.age").show()
        +-----+---+
        | name|age|
        +-----+---+
        |  Bob|  5|
        |Alice|  2|
        +-----+---+

        Outer join on a single column with implicit join condition using column name

        When you provide the column name directly as the join condition, Spark will treat
        both name columns as one, and will not produce separate columns for `df.name` and
        `df2.name`. This avoids having duplicate columns in the output.

        >>> df.join(df2, "name", "outer").sort(sf.desc("name")).show()
        +-----+----+------+
        | name| age|height|
        +-----+----+------+
        |  Tom|NULL|    80|
        |  Bob|   5|    85|
        |Alice|   2|  NULL|
        +-----+----+------+

        Outer join on multiple columns

        >>> df.join(df3, ["name", "age"], "outer").sort("name", "age").show()
        +-----+----+------+
        | name| age|height|

        |Alice|   2|  NULL|
        |Alice|  10|    80|
        |  Bob|   5|  NULL|
        |  Tom|NULL|  NULL|
        +-----+----+------+

        Left outer join on columns

        >>> df.join(df2, "name", "left_outer").show()

        +-----+---+------+

        left (query side), returns up to ``numResults`` rows from ``other`` (base side), ranked
        by ``rankingExpression``.

        The current implementation evaluates the full cross-product of left and right and
        bounds memory per left row by ``numResults``. Index-backed approximate strategies
        (transparent to ``approx`` mode) are planned for a future release; until then,
        pre-filter ``other`` when it is large. Tie-breaking among rows with equal ranking
        values is unspecified.

        Parameters
        ----------
        other : :class:`DataFrame`
            Right (base side) of the join - the candidate pool searched for each row of this
            DataFrame.
        rankingExpression : :class:`Column`
            Scalar expression used to rank candidate rows on the right side.
        numResults : int
            Maximum number of matches per query row. Must be between 1 and 100000.
        mode : str
            Search algorithm contract. Must be one of: ``approx``, ``exact``. ``approx`` allows
            the optimizer to use indexed or other approximate strategies when available;
            ``exact`` forces brute-force evaluation and requires the ranking expression to be
            deterministic.
        direction : str
            ``"distance"`` (smallest value first) or ``"similarity"`` (largest value first).
        joinType : str, keyword-only, optional
            Default ``inner``. Must be one of: ``inner``, ``leftouter``.

        Unpivot a DataFrame from wide format to long format, optionally leaving
        identifier columns set. This is the reverse to `groupBy(...).pivot(...).agg(...)`,
        except for the aggregation, which cannot be reversed.

        This function is useful to massage a DataFrame into a format where some
        columns are identifier columns ("ids"), while all other columns ("values")
        are "unpivoted" to the rows, leaving just two non-id columns, named as given
        by `variableColumnName` and `valueColumnName`.

        When no "id" columns are given, the unpivoted DataFrame consists of only the
        "variable" and "value" columns.

        The `values` columns must not be empty so at least one value must be given to be unpivoted.
        When `values` is `None`, all non-id columns will be unpivoted.

        All "value" columns must share a least common data type. Unless they are the same data type,
        all "value" columns are cast to the nearest common data type. For instance, types
        `IntegerType` and `LongType` are cast to `LongType`, while `IntegerType` and `StringType`
        do not have a common data type and `unpivot` fails.

        ----------
        ids : str, Column, tuple, list
            Column(s) to use as identifiers. Can be a single column or column name,

        * It will compute the defined aggregates (metrics) on all the data that is flowing through
            the Dataset at that point.

        * It will report the value of the defined aggregate columns as soon as we reach a completion
            point. A completion point is either the end of a query (batch mode) or the end of a
            streaming epoch. The value of the aggregates only reflects the data processed since

        The metrics columns must either contain a literal (e.g. lit(42)), or should contain one or
        more aggregate functions (e.g. sum(a) or sum(a + b) + avg(c) - lit(1)). Expressions that

        Parameters
        ----------
        to_replace : bool, int, float, string, list or dict, the value to be replaced.
            If the value is a dict, then `value` is ignored or can be omitted, and `to_replace`
            must be a mapping between a value and a replacement.
        value : bool, int, float, string or None, optional
            The replacement value must be a bool, int, float, string or None. If `value` is a
            list, `value` should be of the same length and type as `to_replace`.
            If `value` is a scalar and `to_replace` is a sequence, then `value` is
            used as a replacement for each item in `to_replace`.
        subset : list, optional
            optional list of column names to consider.
            Columns specified in subset that do not have matching data types are ignored.
            For example, if `value` is a string, and subset contains a non-string column,
            then the non-string column is simply ignored.

        Returns
        -------
        :class:`DataFrame`
            DataFrame with replaced values.

        Calculates the approximate quantiles of numerical columns of a

        The result of this algorithm has the following deterministic bound:
        If the :class:`DataFrame` has N elements and if we request the quantile at
        probability `p` up to error `err`, then the algorithm will return
        a sample `x` from the :class:`DataFrame` so that the *exact* rank of `x` is

        Parameters

        col: str, tuple or list
            Can be a single column name, or a list of names for multiple columns.

            .. versionchanged:: 2.2.0

        probabilities : list or tuple of floats
            a list of quantile probabilities
            Each number must be a float in the range [0, 1].
            For example 0.0 is the minimum, 0.5 is the median, 1.0 is the maximum.
        relativeError : float
            The relative target precision to achieve
            (>= 0). If set to zero, the exact quantiles are computed, which
            could be very expensive. Note that values greater than 1 are
            accepted but gives the same result as 1.

        Returns
        -------
        list
            the approximate quantiles at the given probabilities.

            * If the input `col` is a string, the output is a list of floats.

            * If the input `col` is a list or tuple of strings, the output is also a
                list, but each element in it is a list of floats, i.e., the output
                is a list of list of floats.

        Notes
        -----
        Null values will be ignored in numerical columns before calculation.
        For columns only containing null values, an empty list is returned.

        :class:`DataFrame`
            A new :class:`DataFrame` without the specified columns.

        Notes
        -----
        - When an input is a column name, it is treated literally without further interpretation.
          Otherwise, it will try to match the equivalent expression.
          So dropping a column by its name `drop(colName)` has a different semantic
          with directly dropping the column `drop(col(colName))`.

        Examples
        --------
        Example 1: Drop a column by name.

        |  Tom|
        |Alice|
        |  Bob|

        Example 3: Drop the column that joined both DataFrames on.

        >>> df2 = spark.createDataFrame([(80, "Tom"), (85, "Bob")], ["height", "name"])
        >>> df.join(df2, df.name == df2.name).drop('name').sort('age').show()

        """
        Return a `Column` object for an EXISTS Subquery.

        The `exists` method provides a way to create a boolean column that checks for the presence
        of related records in a subquery. When applied within a `DataFrame`, this method allows you
        to filter rows based on whether matching records exist in the related dataset. The resulting
        `Column` object can be used directly in filtering conditions or as a computed column.

            A `Column` object representing an EXISTS subquery

        Examples
        --------
        Setup sample data for customers and orders.
