pyspark.sql.DataFrame.agg¶

DataFrame.agg(*exprs: Union[pyspark.sql.column.Column, Dict[str, str]]) → pyspark.sql.dataframe.DataFrame¶

Aggregate on the entire DataFrame without groups (shorthand for df.groupBy().agg()).

Examples

>>> df.agg({"age": "max"}).collect()
[Row(max(age)=5)]
>>> from pyspark.sql import functions as F
>>> df.agg(F.min(df.age)).collect()
[Row(min(age)=2)]
