pyspark.sql.DataFrame.dropna

DataFrame.dropna(how: str = 'any', thresh: Optional[int] = None, subset: Union[str, Tuple[str, …], List[str], None] = None) → pyspark.sql.dataframe.DataFrame

Returns a new DataFrame omitting rows with null values. DataFrame.dropna() and DataFrameNaFunctions.drop() are aliases of each other.

Parameters

howstr, optional

‘any’ or ‘all’. If ‘any’, drop a row if it contains any nulls. If ‘all’, drop a row only if all its values are null.

thresh: int, optional

default None If specified, drop rows that have less than thresh non-null values. This overwrites the how parameter.

subsetstr, tuple or list, optional

optional list of column names to consider.

Examples

>>> df4.na.drop().show()
+---+------+-----+
|age|height| name|
+---+------+-----+
| 10|    80|Alice|
+---+------+-----+
