cudf.Series.size#
- property Series.size: int[source]#
Return the number of elements in the underlying data.
- Returns:
- sizeSize of the DataFrame / Index / Series / MultiIndex
Examples
Size of an empty dataframe is 0.
>>> import cudf >>> df = cudf.DataFrame() >>> df Empty DataFrame Columns: [] Index: [] >>> df.size 0 >>> df = cudf.DataFrame(index=[1, 2, 3]) >>> df Empty DataFrame Columns: [] Index: [1, 2, 3] >>> df.size 0
DataFrame with values
>>> df = cudf.DataFrame({'a': [10, 11, 12], ... 'b': ['hello', 'rapids', 'ai']}) >>> df a b 0 10 hello 1 11 rapids 2 12 ai >>> df.size 6 >>> df.index RangeIndex(start=0, stop=3) >>> df.index.size 3
Size of an Index
>>> index = cudf.Index([]) >>> index Index([], dtype='float64') >>> index.size 0 >>> index = cudf.Index([1, 2, 3, 10]) >>> index Index([1, 2, 3, 10], dtype='int64') >>> index.size 4
Size of a MultiIndex
>>> midx = cudf.MultiIndex( ... levels=[["a", "b", "c", None], ["1", None, "5"]], ... codes=[[0, 0, 1, 2, 3], [0, 2, 1, 1, 0]], ... names=["x", "y"], ... ) >>> midx MultiIndex([( 'a', '1'), ( 'a', '5'), ( 'b', <NA>), ( 'c', <NA>), (<NA>, '1')], names=['x', 'y']) >>> midx.size 5
